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
