How do if-else statements work in JavaScript?

If-else statements allow you to execute different code based on certain conditions. For example, you can check if a variable is true or false and run code accordingly.

Can you give me a simple example?

Sure! Here's a basic example:

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

What happens if I have multiple conditions?

You can use else if to check multiple conditions. For example:

if (age < 13) {
    console.log('You are a child.');
} else if (age < 18) {
    console.log('You are a teenager.');
} else {
    console.log('You are an adult.');
}

Are there any best practices for using if-else?

Yes! Keep your conditions simple, avoid deep nesting, and consider using switch statements for multiple cases to improve readability.
