Step 1: Introduction to JavaScript
JavaScript is a programming language that allows you to make web pages interactive.
It’s used for adding dynamic content, handling user events, and creating complex web applications.
Step 2: Variables and Data Types
Variables are used to store data. Common data types include numbers, strings, and booleans.
Let’s see some examples:
let name = "John Doe";
let age = 30;
let isStudent = true;
Step 3: Operators
Operators allow you to perform operations on values.
Some common operators include: +, -, *, /, ==, !==, <, >
+ 5 3; // 8
= 10;
!= 5; // false
Step 4: Let's make a simple alert
Let's print some text to the browser using JavaScript.
alert("Hello, world!");
Step 5: Control Flow - If Statements
Control flow lets you control the sequence of your program.
We can make sure something happens based on whether a condition is true or false.
if (age > 18) {
console.log("You are an adult.");
} else {
console.log("You are a minor.");
}
