console.log("Hello World");
Here, you are telling JavaScript to display:
Hello WorldThink of programming like giving instructions to a very literal assistant — it does exactly what you tell it to do. 2️⃣ What is JavaScript? JavaScript is a programming language mainly used to make websites and applications interactive. It can be used for: 🔹 Websites 🔹 Web applications 🔹 Backend development 🔹 Mobile applications 🔹 Desktop applications 🔹 APIs 🔹 Automation 🔹 AI-powered applications 3️⃣ How JavaScript Works When you write:
let name = "Rahul";
console.log(name);
JavaScript produces:
RahulJavaScript can run in different environments: 🌐 Browser → Chrome, Edge, Firefox, etc. 🟢 Node.js → Server-side JavaScript ⚡ Other runtimes → Modern JavaScript applications 4️⃣ Variables Variables are used to store values.
let age = 25;
const country = "India";
Here:
"age"→ stores
"25"/
"country"→ stores
"India"The two most important keywords:
let
const
letcan be reassigned.
constcannot be reassigned. 5️⃣ Basic Data Types
let name = "Rahul"; // String
let age = 25; // Number
let isStudent = true; // Boolean
let result; // Undefined
let value = null; // Null
Later, you'll learn:
🔹 Objects
🔹 Arrays
🔹 Functions
🔹 Symbols
🔹 BigInt
6️⃣ Operators
let a = 10;
let b = 5;
console.log(a + b); // 15
You'll eventually learn:
➕ Arithmetic operators
🔍 Comparison operators
🧠 Logical operators
📝 Assignment operators
❓ Ternary operator
7️⃣ Conditions
let age = 20;
if (age >= 18) {
console.log("You can vote");
}
8️⃣ Loops
for (let i = 1; i <= 5; i++) {
console.log(i);
}
Output:
1 2 3 4 5Later you'll learn: 🔹 for🔹 while🔹 do...while🔹 for...of🔹 for...in 9️⃣ Debugging You need to learn how to: 🔹 Read error messages 🔹 Find the problematic line 🔹 Use
console.log()
🔹 Use browser Developer Tools
🔹 Use breakpoints
