Module 1: Introduction to Web Development
Module 1 Summary – Introduction to Web Development In this module, you learned the basics of web development and how the internet works. You understood the difference between frontend, backend, and full stack development and explored the client–server model that powers websites. You also set up your development environment with browser and VS Code, and created a simple project folder structure. Finally, you discovered the roles of HTML, CSS, and JavaScript in building a website — HTML gives the structure, CSS adds design and style, JavaScript makes it interactive. By completing this module, you now have the foundation to start coding websites.

Module 6: HTML+CSS+JS Project (Mini Project)
In this module, students will apply all their learning from HTML, CSS, and JavaScript by creating a mini project. This hands-on experience helps students understand real-world web development, integrate multiple concepts, and gain confidence in building interactive web pages. Key Highlights: Design a complete webpage with HTML structure. Style the page using CSS (colors, layout, fonts, responsive design). Add interactivity with JavaScript (DOM manipulation, event handling, form validation). Practice project planning, coding, and debugging. Prepare students for real-world web development tasks.

Lesson 4.12: Introduction to JSON

JSON (JavaScript Object Notation) is a lightweight data format used for storing and exchanging data between a server and a web application. It is easy to read and write for humans and easy to parse for machines.

1. Why JSON?

  • Works perfectly with JavaScript.

  • Language-independent and widely used in APIs.

  • Simple format to store structured data like objects and arrays.

2. JSON Syntax

  • Data is represented as key-value pairs.

  • Keys must be strings in double quotes.

  • Values can be: string, number, boolean, array, object, or null.

Example:

 
{
"name": "Raman",
"age": 25,
"isStudent": true,
"skills": ["HTML", "CSS", "JavaScript"],
"address": {
"city": "Delhi",
"country": "India"
}
}

3. JSON vs JavaScript Object

  • JavaScript Object:

 
let person = {name: "Raman", age: 25};

  • JSON:

 
{"name": "Raman", "age": 25}

Note: JSON keys must always be double-quoted strings.

4. Using JSON in JavaScript

a) Convert Object to JSON (stringify)

 
let person = {name: "Raman", age: 25};
let jsonData = JSON.stringify(person);
console.log(jsonData); // '{"name":"Raman","age":25}'

b) Convert JSON to Object (parse)

 
let jsonData = '{"name":"Raman","age":25}';
let personObj = JSON.parse(jsonData);
console.log(personObj.name); // Raman

5. Practical Use

  • Fetch data from APIs:

 
fetch("https://api.example.com/users")
.then(response => response.json())
.then(data => console.log(data));

  • Store structured data in LocalStorage:

 
let user = {name: "Raman", age: 25};
localStorage.setItem("user", JSON.stringify(user));
let storedUser = JSON.parse(localStorage.getItem("user"));
console.log(storedUser.name); // Raman

✅ Summary:

  • JSON = Lightweight format for data storage & exchange.

  • Always use double quotes for keys.

  • Convert between JS objects ↔ JSON strings using JSON.stringify() and JSON.parse().

  • Widely used in APIs, LocalStorage, and server communication.
