Understanding JavaScript Conditional Statements

Introduction to JavaScript Conditional Statements

Conditional statements are used to execute different blocks of code based on conditions.

Step 1: If Statement

The if statement is used to execute a block of code if a condition is true.

let x = 5;
if (x > 10) {
    console.log('x is greater than 10');
} else {
    console.log('x is less than or equal to 10');
}

Step 2: If-Else Statement

The if-else statement is used to execute a block of code if a condition is true, and another block of code if the condition is false.

let x = 5;
if (x > 10) {
    console.log('x is greater than 10');
} else if (x == 5) {
    console.log('x is equal to 5');
} else {
    console.log('x is less than 5');
}

Step 3: Switch Statement

The switch statement is used to execute a block of code based on the value of a variable.

let color = 'red';
switch (color) {
    case 'red':
        console.log('The color is red');
        break;
    case 'green':
        console.log('The color is green');
        break;
    default:
        console.log('The color is not red or green');
}

By following these steps, you can learn how to use conditional statements in JavaScript.
