What is a try-catch block in programming?

What is a try-catch block in programming?

A try-catch block is used to handle exceptions in programming. It allows you to try a block of code and catch any errors that occur.

Can you give me an example of how to use a try-catch block?

Sure! Here's a simple example in JavaScript:

try {
    // Code that may throw an error
    let result = riskyFunction();
} catch (error) {
    // Code to handle the error
    console.error('An error occurred:', error);
}

What happens if an error occurs outside the try block?

If an error occurs outside the try block, it won't be caught by the catch block, and the program will terminate unless handled elsewhere.

Are there any best practices for using try-catch?

Yes, some best practices include only using try-catch for code that may throw exceptions, and logging errors for debugging.
