JavaScript Conditional Statements: If/Else and Switch

Introduction to JavaScript Conditional Statements

Conditional statements are used to control the flow of a program based on certain conditions. In this tutorial, we will cover the basics of JavaScript conditional statements.

If/Else Statements

The if statement is used to execute a block of code if a certain condition is true. The else statement is used to execute a block of code if the condition is false. Here is an example of how to use an if/else statement:

let age = 25;
if (age >= 18) {
  console.log('You are an adult.');
} else {
  console.log('You are a minor.');
}

Switch Statements

The switch statement is used to execute a block of code based on the value of a variable. Here is an example of how to use a switch statement:

let day = 'Monday';
switch (day) {
  case 'Monday':
    console.log('Today is Monday.');
    break;
  case 'Tuesday':
    console.log('Today is Tuesday.');
    break;
  default:
    console.log('Today is not Monday or Tuesday.');
}
