🔧 JavaScript Error Handling — Try, Catch, Throw, Finally

Error handling in JavaScript is important to deal with mistakes or problems that happen while your code is running. JavaScript gives you a few simple tools to handle errors and keep your code from crashing:

try: You use this to test a piece of code. If everything works fine, it runs without issues.

catch: If something goes wrong in the "try" part, the "catch" block will handle the error and stop the program from crashing.

throw: This is used to create your own errors. You can decide when to throw an error based on certain conditions.

finally: This block of code always runs, whether there's an error or not. It's useful for cleaning up resources, like closing a file or stopping a process.
