What is the difference between throw and return in JavaScript?

Can you explain the difference between throw and return in JavaScript?

Sure! In JavaScript, 'return' is used to exit a function and send a value back to the caller, while 'throw' is used to create an exception that interrupts the normal flow of execution.

Can you give me an example of how throw works?

Absolutely! Here's a simple example:

function checkAge(age) {
    if (age < 18) {
        throw new Error('You must be at least 18 years old.');
    }
    return 'Access granted';
}

In this case, if the age is less than 18, an error is thrown.

What happens if I use return inside a try block?

If you use return inside a try block, it will return the value to the caller, but if an error occurs, the catch block will handle it. Here's an example:

function safeDivide(a, b) {
    try {
        return a / b;
    } catch (error) {
        console.error('Error:', error);
    }
}

So, can I use throw to return a value?

Not exactly. 'throw' is meant for signaling errors, not for returning values. If you want to return a value, you should use 'return'.
