JavaScript Error Handling

In this tutorial, you’ll learn how to handle errors in JavaScript using a try / catch block.

From time to time you’ll come up against errors in your code. I’m not talking about mistakes that you’ve made by incorrectly using a variable or similar for example but rather something that might be unexpected.

A specific example may be when a response from a network request is returned incorrectly or when you expect a function to be defined when it has yet to be.

In the tutorial, you’ll learn how to use JavaScript’s try catch keywords to wrap potentially unsafe code. This will enable you to expect errors and handle them appropriately.
