JavaScript: Error Handling with try…catch…finally

Handle errors in JavaScript without crashing your app or hiding problems. Learn try, catch and finally, the built-in error types, throwing your own errors with a cause, catching only what you expect, and handling errors in async code with await, including the important fact that fetch does not reject on HTTP error statuses.
