JavaScript Exception Handling

Exceptions are run-time errors.

A try catch block allows you to control program flow after run-time errors.

Error types, such as ReferenceError and TypeError are thrown to the catch block.

You can throw errors according to your own logic in the try block.

A finally block always executes.

You can create custom Errors with custom message properties.

Try blocks can be nested within catch blocks.
