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, the catch block will execute.

Can I have multiple catch blocks?

No, JavaScript only allows one catch block per try block. However, you can use if-else statements inside the catch block to handle different error types.

What happens if I don't use try-catch?

If you don't use try-catch and an error occurs, the script will stop executing, and you'll see an error message in the console.
