Exception Handling - Javascript In Depth

We look at exception handling in Javascript together. Specifically, we look at the "throw" statement as well as the try/catch control flow construct. These allow us to handle errors in our program in pre-determined ways and let us control whether we want the program to continue or crash.
This concept will come up everywhere in Javascript and we are only scratching the surface in this video. However, this will give us a good point to jump off from for things like async/await as well as most basic error handling scenarios.
This is part of a series where we go over Javascript in depth to learn programming concepts as well as web development: • Javascript In Depth

You are the greatest teacher.
I can't even begin to explain how much you helped me with this playlist (and believe me, I've tried many courses before)! Your teaching method works great for me :)

When attempting to execute our code and dealing with errors, we encounter issues with files like 'throw.js' that cannot be executed without utilizing functions such as 'try-scope.js' and 'try-catch-object.js'. Would it be advisable to delete the 'throw.js' file, considering whether it still serves a significant purpose now that the code can run smoothly?

[@TechWithNader]

Yup! We would always want to try/catch things and catch any throws that may happen in our code. Usually you would be careful to catch the throw higher up in the call stack so it doesn't stop the program like we saw here 😊
