What is the try-catch statement in JavaScript?

Can you explain what the try-catch statement does in JavaScript?

Sure! The try-catch statement is used to handle exceptions in JavaScript. It allows you to test a block of code for errors and catch those errors if they occur.

How do I use try-catch in my code?

You can use it like this:

try {
    // Code that may throw an error
} catch (error) {
    // Code to handle the error
}

This way, if an error occurs in the try block, it will be caught in the catch block.

Can you give me an example of a try-catch in action?

Absolutely! Here's a simple example:

try {
    let result = riskyFunction(); // This might throw an error
} catch (error) {
    console.error('Error occurred:', error);
}

In this case, if riskyFunction throws an error, it will be caught and logged.

What types of errors can I catch with try-catch?

You can catch any runtime errors, such as TypeError, ReferenceError, and custom errors thrown using the throw statement.
