How do I use try-catch in programming?

Can you explain how to use try-catch in programming?

Sure! The try-catch statement is used to handle exceptions in your code. You place the code that might throw an error inside the 'try' block, and if an error occurs, the 'catch' block will handle it.

Can you give me an example of how it works?

Of course! 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 I don't use try-catch?

If you don't use try-catch, any error that occurs will cause your program to crash, and it won't be able to recover from it.

Are there any best practices for using try-catch?

Yes! It's best to use try-catch only around code that you expect might fail, and avoid using it for control flow. Also, always log the error for debugging.
