Phase 0 — Foundations (Weeks 1–2)

Before writing a single line of code, get comfortable with the tools every developer uses.

How the web works

User types URL → DNS lookup → TCP connection → HTTP request → Server response → Browser renders

Key concepts to understand:

Browser renders HTML, CSS, JavaScript
HTTP/HTTPS is the communication protocol
Client = browser; Server = the computer serving your files/data
Domain points to an IP address via DNS
Static vs dynamic websites (static = same for everyone; dynamic = personalised content)

Terminal basics

You don't need to be a Linux expert, but learn these:

pwd           # where am I?
ls            # list files
cd folder/    # change directory
mkdir mysite  # create folder
touch index.html  # create file
cp a.txt b.txt    # copy file
mv a.txt b.txt    # move / rename
rm file.txt       # delete file

Text editor

Use VS Code — free, fast, and has the best extension ecosystem. Install these extensions:

Prettier (auto-formatting)
ESLint (JavaScript linting)
Live Server (instant browser reload)
GitLens (better Git integration)

Phase 1 — HTML (Weeks 3–5)

HTML is the skeleton of every webpage. It defines structure — not appearance.

Core concepts

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>My First Page</title>
</head>
<body>
  <header>
    <nav>
      <a href="/">Home</a>
      <a href="/about">About</a>
    </nav>
  </header>

  <main>
    <h1>Welcome</h1>
    <p>This is a paragraph with <strong>bold</strong> and <em>italic</em> text.</p>

    <ul>
      <li>Item one</li>
      <li>Item two</li>
    </ul>

    <img src="photo.jpg" alt="A descriptive alt text" />

    <a href="https://example.com">External link</a>
  </main>

  <footer>
    <p>© 2025 My Site</p>
  </footer>
</body>
</html>

Semantic HTML elements

Element	Purpose
`<header>`	Top section of page or article
`<nav>`	Navigation links
`<main>`	Primary content (one per page)
`<article>`	Self-contained content (blog post, product card)
`<section>`	Thematic grouping within a page
`<aside>`	Supplementary content (sidebar)
`<footer>`	Bottom section
`<figure>` / `<figcaption>`	Image with caption
`<time>`	Dates and times

Semantic HTML matters for:

SEO — search engines understand your content structure
Accessibility — screen readers navigate by landmarks
Maintainability — code is self-documenting

HTML forms

<form action="/submit" method="POST">
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" required />

  <label for="message">Message:</label>
  <textarea id="message" name="message" rows="4"></textarea>

  <button type="submit">Send</button>
</form>

Phase 2 — CSS (Weeks 6–11)

CSS controls appearance — colors, fonts, spacing, layout.

The box model

Every element is a box:

┌──────────────────────────┐
│         margin           │
│  ┌────────────────────┐  │
│  │      border        │  │
│  │  ┌──────────────┐  │  │
│  │  │   padding    │  │  │
│  │  │  ┌────────┐  │  │  │
│  │  │  │content │  │  │  │
│  │  │  └────────┘  │  │  │
│  │  └──────────────┘  │  │
│  └────────────────────┘  │
└──────────────────────────┘

/* Always set this at the top */
*, *::before, *::after {
  box-sizing: border-box; /* padding/border included in width */
}

.card {
  width: 300px;
  padding: 20px;
  border: 1px solid #e5e7eb;
  border-radius: 8px;
  margin: 16px;
}

Flexbox (one-dimensional layout)

.container {
  display: flex;
  justify-content: space-between; /* horizontal */
  align-items: center;            /* vertical */
  gap: 16px;
  flex-wrap: wrap;
}

.item {
  flex: 1;          /* grow equally */
  min-width: 200px; /* don't shrink below 200px */
}

Property	Values	Effect
`justify-content`	`flex-start`, `center`, `space-between`, `space-around`, `space-evenly`	Main axis alignment
`align-items`	`stretch`, `center`, `flex-start`, `flex-end`, `baseline`	Cross axis alignment
`flex-direction`	`row`, `column`, `row-reverse`, `column-reverse`	Main axis direction
`flex-wrap`	`nowrap`, `wrap`, `wrap-reverse`	Allow wrapping
`gap`	length	Space between items

CSS Grid (two-dimensional layout)

.grid {
  display: grid;
  grid-template-columns: repeat(3, 1fr); /* 3 equal columns */
  gap: 24px;
}

/* Responsive grid — columns collapse on small screens */
.responsive-grid {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
  gap: 16px;
}

Responsive design

/* Mobile first */
.container {
  padding: 16px;
  max-width: 100%;
}

/* Tablet */
@media (min-width: 768px) {
  .container {
    padding: 24px;
    max-width: 720px;
    margin: 0 auto;
  }
}

/* Desktop */
@media (min-width: 1024px) {
  .container {
    max-width: 960px;
  }
}

Standard breakpoints:

480px — large phones
768px — tablets
1024px — laptops
1280px — desktops

CSS custom properties (variables)

:root {
  --color-primary: #3b82f6;
  --color-text: #111827;
  --spacing-sm: 8px;
  --spacing-md: 16px;
  --border-radius: 6px;
  --font-body: 'Inter', sans-serif;
}

.button {
  background: var(--color-primary);
  padding: var(--spacing-sm) var(--spacing-md);
  border-radius: var(--border-radius);
}

Phase 3 — JavaScript (Weeks 12–23)

JavaScript makes pages interactive — form validation, dynamic content, API calls.

JavaScript basics

// Variables
const name = 'Alice';     // immutable binding
let count = 0;            // mutable
// var is outdated — avoid it

// Functions
function greet(name) {
  return `Hello, ${name}!`;
}

// Arrow function
const double = (n) => n * 2;

// Conditionals
if (count > 10) {
  console.log('high');
} else if (count > 5) {
  console.log('medium');
} else {
  console.log('low');
}

// Arrays
const fruits = ['apple', 'banana', 'cherry'];
fruits.push('date');
const upper = fruits.map(f => f.toUpperCase());
const long = fruits.filter(f => f.length > 5);

// Objects
const user = { name: 'Alice', age: 30 };
const { name: userName, age } = user; // destructuring

DOM manipulation

// Select elements
const btn = document.querySelector('#my-button');
const items = document.querySelectorAll('.item');

// Modify content
btn.textContent = 'Click me';
btn.classList.add('active');
btn.classList.toggle('hidden');

// Events
btn.addEventListener('click', (event) => {
  event.preventDefault();
  console.log('Button clicked!');
});

// Create elements
const div = document.createElement('div');
div.textContent = 'New content';
document.body.appendChild(div);

Async JavaScript

// Fetch data from an API
async function fetchUsers() {
  try {
    const response = await fetch('https://api.example.com/users');
    if (!response.ok) throw new Error(`HTTP error: ${response.status}`);
    const data = await response.json();
    return data;
  } catch (error) {
    console.error('Fetch failed:', error);
  }
}

// Use it
fetchUsers().then(users => {
  users.forEach(user => console.log(user.name));
});

What to learn in JavaScript

Topic	Why it matters
Variables, data types, operators	Foundation
Functions, arrow functions, scope	Code organisation
Arrays and array methods (map/filter/reduce)	Data transformation
Objects and destructuring	Working with data
DOM manipulation	Making pages interactive
Events and event delegation	User interaction
`fetch` and async/await	Calling APIs
Error handling (try/catch)	Robust code
ES6+ features (spread, optional chaining, nullish coalescing)	Modern syntax
Modules (import/export)	Code splitting

Phase 4 — Git (Weeks 24–25)

Version control is non-negotiable. Every professional developer uses Git.

Essential commands

git init                    # start new repo
git clone <url>             # copy existing repo
git status                  # see what changed
git add .                   # stage all changes
git commit -m "Add feature" # save snapshot
git push origin main        # upload to GitHub
git pull                    # download latest changes

# Branching
git checkout -b feature/login  # create + switch branch
git merge feature/login         # merge into current branch
git branch -d feature/login     # delete branch after merge

Git workflow

main branch (always deployable)
  └── feature/user-auth    ← you work here
  └── fix/navbar-bug       ← colleague works here
  └── feature/dark-mode    ← another feature

Create a GitHub account and push every project you build. Employers look at your GitHub profile.

Phase 5 — Front-end framework (Weeks 26–35)

Once you're comfortable with JavaScript, learn one front-end framework.

Which framework?

Framework	Learning curve	Job demand	Best for
React	Moderate	Very high (60-70% of jobs)	General web apps, startups, large teams
Vue 3	Low	Moderate	Smaller teams, beginners, existing PHP/Laravel projects
Svelte	Low	Low but growing	Performance-focused, simpler mental model
Angular	High	Moderate	Large enterprise projects, TypeScript-first teams

Recommendation for beginners: React. It has the most jobs, tutorials, and community support.

React fundamentals

import { useState, useEffect } from 'react';

function UserList() {
  const [users, setUsers] = useState([]);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    fetch('/api/users')
      .then(res => res.json())
      .then(data => {
        setUsers(data);
        setLoading(false);
      });
  }, []); // empty array = run once on mount

  if (loading) return <p>Loading...</p>;

  return (
    <ul>
      {users.map(user => (
        <li key={user.id}>{user.name}</li>
      ))}
    </ul>
  );
}

React concepts to learn

Concept	What it does
Components	Reusable UI pieces
Props	Pass data into components
State (`useState`)	Local mutable data
Effect (`useEffect`)	Side effects (data fetching, subscriptions)
Context (`useContext`)	Share data without prop drilling
Ref (`useRef`)	Access DOM elements directly
Memo (`useMemo`, `useCallback`)	Optimise re-renders
React Router	Multi-page navigation in a SPA
Data fetching (TanStack Query)	Server state management

Phase 6 — Back-end basics (Weeks 36–43)

The back end handles data storage, business logic, authentication, and APIs.

Choose a language

Language	Framework	Best for
JavaScript/TypeScript	Node.js + Express / Fastify	Full-stack JS teams, shared code with front end
Python	FastAPI / Django	Data science, ML integration, clean syntax
Go	standard library / Gin	High-performance APIs, microservices
PHP	Laravel	Traditional web apps, WordPress ecosystem

Recommendation for beginners: Node.js — same language as your front end, huge ecosystem.

Node.js + Express basics

import express from 'express';

const app = express();
app.use(express.json());

// In-memory "database" for learning
const users = [
  { id: 1, name: 'Alice' },
  { id: 2, name: 'Bob' },
];

// GET all users
app.get('/api/users', (req, res) => {
  res.json(users);
});

// GET single user
app.get('/api/users/:id', (req, res) => {
  const user = users.find(u => u.id === Number(req.params.id));
  if (!user) return res.status(404).json({ error: 'User not found' });
  res.json(user);
});

// POST create user
app.post('/api/users', (req, res) => {
  const user = { id: Date.now(), ...req.body };
  users.push(user);
  res.status(201).json(user);
});

// DELETE user
app.delete('/api/users/:id', (req, res) => {
  const index = users.findIndex(u => u.id === Number(req.params.id));
  if (index === -1) return res.status(404).json({ error: 'Not found' });
  users.splice(index, 1);
  res.status(204).send();
});

app.listen(3000, () => console.log('Server running on port 3000'));

Phase 7 — Databases (Weeks 44–47)

Almost every web app needs to store data persistently.

SQL vs NoSQL

Aspect	SQL (relational)	NoSQL (document)
Structure	Tables with fixed schema	Flexible JSON documents
Relationships	JOINs, foreign keys	Embedded documents or references
Query language	SQL	Database-specific API
Best for	Structured data, complex queries, transactions	Flexible schema, horizontal scale
Examples	PostgreSQL, MySQL, SQLite	MongoDB, DynamoDB, Firestore

Recommendation: Learn SQL first. SQL knowledge transfers across databases, it's tested in interviews, and it handles 80% of use cases.

SQL essentials

-- Create table
CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  email VARCHAR(255) UNIQUE NOT NULL,
  name VARCHAR(100) NOT NULL,
  created_at TIMESTAMP DEFAULT NOW()
);

-- Insert
INSERT INTO users (email, name) VALUES ('alice@example.com', 'Alice');

-- Select
SELECT id, name, email FROM users WHERE name LIKE 'A%' ORDER BY name;

-- Update
UPDATE users SET name = 'Alice Smith' WHERE id = 1;

-- Delete
DELETE FROM users WHERE id = 1;

-- JOIN
SELECT orders.id, users.name, orders.total
FROM orders
JOIN users ON orders.user_id = users.id
WHERE orders.total > 100;

ORM (Object-Relational Mapper)

Don't write raw SQL for every query. Use an ORM:

Language	Popular ORMs
JavaScript/TypeScript	Prisma, Drizzle, Sequelize
Python	SQLAlchemy, Django ORM
Java	Hibernate, Spring Data JPA
PHP	Eloquent (Laravel)

// Prisma example
const user = await prisma.user.create({
  data: { email: 'alice@example.com', name: 'Alice' },
});

const users = await prisma.user.findMany({
  where: { name: { startsWith: 'A' } },
  orderBy: { name: 'asc' },
});

Phase 8 — APIs (Weeks 48–50)

REST API conventions

Method	Path	Action
GET	`/api/users`	List all users
GET	`/api/users/42`	Get user 42
POST	`/api/users`	Create user
PUT	`/api/users/42`	Replace user 42
PATCH	`/api/users/42`	Update fields on user 42
DELETE	`/api/users/42`	Delete user 42

Authentication basics

import jwt from 'jsonwebtoken';
import bcrypt from 'bcrypt';

// Register
app.post('/api/auth/register', async (req, res) => {
  const { email, password, name } = req.body;
  const hashedPassword = await bcrypt.hash(password, 12);
  const user = await prisma.user.create({
    data: { email, name, password: hashedPassword },
  });
  res.status(201).json({ id: user.id, email: user.email });
});

// Login
app.post('/api/auth/login', async (req, res) => {
  const { email, password } = req.body;
  const user = await prisma.user.findUnique({ where: { email } });
  if (!user || !await bcrypt.compare(password, user.password)) {
    return res.status(401).json({ error: 'Invalid credentials' });
  }
  const token = jwt.sign({ userId: user.id }, process.env.JWT_SECRET, {
    expiresIn: '7d',
  });
  res.json({ token });
});

// Protected route middleware
function authenticate(req, res, next) {
  const token = req.headers.authorization?.split(' ')[1];
  if (!token) return res.status(401).json({ error: 'Unauthorized' });
  try {
    req.user = jwt.verify(token, process.env.JWT_SECRET);
    next();
  } catch {
    res.status(401).json({ error: 'Invalid token' });
  }
}

Phase 9 — Deployment (Weeks 51–53)

Your app needs to run somewhere accessible to the internet.

Deployment options

Platform	Type	Free tier	Best for
Vercel	Serverless/static	Yes	Next.js, static sites, front-end
Netlify	Static/serverless	Yes	Static sites, JAMstack
Railway	Full server	Yes ($5 credit)	Node.js, Postgres, Redis
Render	Full server	Yes (spins down)	Full-stack apps, databases
Fly.io	Containers	Yes	Docker containers, global edge
AWS / GCP / Azure	Cloud	Limited	Production, enterprise

Deploying a React + Node.js app (example: Vercel + Railway)

# Front end (React/Next.js) → Vercel
npx vercel                    # follow prompts

# Back end (Node.js API) → Railway
# Push to GitHub → connect Railway to your repo → deploy

Environment variables

# .env (never commit this!)
DATABASE_URL=postgresql://user:pass@localhost:5432/mydb
JWT_SECRET=super-secret-key-at-least-32-chars
PORT=3000

// Load in Node.js
import 'dotenv/config';
const db = process.env.DATABASE_URL;

Basics of HTTPS and domains

Every production site needs HTTPS — Vercel/Netlify/Railway handle this automatically
Buy a domain from Namecheap, Cloudflare, or Google Domains
Point domain's DNS A record to your server IP

Not using version control	Lose work, can't collaborate	Commit every project from day one
Copying code without understanding it	Can't explain it in interviews	Type it out, then modify it
Skipping the basics (HTML, CSS)	Weak foundation shows in interviews	Master HTML/CSS before JavaScript
Learning multiple frameworks simultaneously	Shallow knowledge of all, expert in none	One framework at a time
Not deploying projects	Portfolio of local apps means nothing	Deploy everything
Ignoring accessibility	Excludes users, fails interviews	Add alt text, labels, semantic HTML

Web developer vs related roles

Role	Similarity	Key difference
Web developer	—	Builds websites and web apps
Software engineer	High	More general — can be desktop, embedded, systems
DevOps engineer	Medium	Focuses on infrastructure, CI/CD, cloud
Data engineer	Low	Focuses on data pipelines, ETL, warehouses
Mobile developer	Medium	Same languages sometimes, but native mobile UI
UX designer	Low	Designs user experience — not always coding

Frequently asked questions

Do I need a degree to become a web developer? No. Hiring managers care about your portfolio, not your degree. Many successful developers are self-taught. A degree helps at large companies that filter by credential, but bootcamp grads and self-taught developers land jobs every day.

How long does it take to get a junior job? With full-time study: 9–12 months. With part-time study while working: 18–24 months. The biggest variable is the quality of your portfolio projects and how much you actively apply and network.

Should I learn TypeScript as a beginner? Not immediately. Learn JavaScript thoroughly first. After 3–4 months of JavaScript, add TypeScript — the payoff is huge (fewer bugs, better tooling, required at most companies for mid/senior roles).

Front end or back end first? Front end. The visual feedback keeps you motivated, you can show others what you built, and every job needs front-end skills. Once you have a foundation, back end clicks much faster.

Which framework should I learn — React, Vue, or Angular? React for maximum job opportunities. Vue if you find React's mental model confusing. Angular only if you specifically target enterprise roles. Don't learn all three — go deep on one.

What should I put in my portfolio? 2–3 real, deployed projects that solve an actual problem — not clone apps. Include source code on GitHub, a live link, and a README explaining what it does, why you built it, and what you learned. Quality beats quantity.
