JavaScript Conditionals

JavaScript Conditionals

Conditional statements allow you to execute code based on certain conditions.

if Statement

The if statement executes a block of code if a specified condition is true.

let age = 18;
if (age >= 18) {
    console.log("You are an adult.");
}

if...else Statement

The if...else statement provides an alternative block of code if the condition is false.

let age = 16;
if (age >= 18) {
    console.log("You are an adult.");
} else {
    console.log("You are a minor.");
}

else if Statement

The else if statement allows you to test multiple conditions.

let score = 85;
if (score >= 90) {
    console.log("Grade: A");
} else if (score >= 80) {
    console.log("Grade: B");
} else {
    console.log("Grade: C");
}

switch Statement

The switch statement is used to test multiple conditions:

let day = 3;
switch (day) {
    case 1:
        console.log("Monday");
        break;
    case 2:
        console.log("Tuesday");
        break;
    case 3:
        console.log("Wednesday");
        break;
    default:
        console.log("Invalid day");
}
