Error Handling and Debugging

Error Handling and Debugging

Error handling and debugging are crucial aspects of JavaScript development that help identify and resolve issues in the code.

Proper error handling ensures that unexpected errors are caught and gracefully handled, while effective debugging techniques help developers find and fix bugs during the development process.

Handling Exceptions and Errors

Exceptions and errors occur when the program encounters unexpected situations or incorrect data. JavaScript provides the try...catch statement for handling exceptions.

Throwing Custom Errors

Developers can throw custom errors using the throw keyword to indicate specific exceptional conditions.
