What are nested if-else statements in JavaScript?

Can you explain what nested if-else statements are in JavaScript?

Sure! Nested if-else statements are if-else statements placed inside another if-else statement. They allow for more complex decision-making.

Can you give me an example of how to use nested if-else in code?

Of course! Here's a simple example:

let age = 20;
if (age >= 18) {
    if (age >= 21) {
        console.log('You can drink alcohol.');
    } else {
        console.log('You can vote but not drink alcohol.');
    }
} else {
    console.log('You are a minor.');
}

What happens if I don't use nested if-else?

Without nested if-else, you might not be able to handle multiple conditions effectively, leading to less clear code.

Are there any alternatives to nested if-else?

Yes! You can use switch statements or logical operators like && and || to simplify your conditions.
