When Should You "throw" A JavaScript Error Or Exception? - JavaScript Toolkit

When Should You "throw" A JavaScript Error Or Exception? Are you curious about how to handle errors and exceptions in JavaScript? In this detailed video, we’ll explain everything you need to know about when and why to throw errors in your code. We’ll start by discussing the importance of making problems visible in your application and how throwing errors can help you do that effectively. You’ll learn about common scenarios where errors should be used, such as validating user input, handling missing resources, or preventing unsafe operations. We’ll also cover the differences between errors and exceptions in JavaScript, highlighting when each should be used and how to create custom error objects for more specific issues. Additionally, we’ll explain how throwing errors interacts with control flow, especially in asynchronous JavaScript like promises and async functions. You’ll discover how try and catch blocks work to manage errors gracefully, preventing your app from crashing unexpectedly. We’ll also share best practices on when to avoid throwing errors — for example, in cases where user input can be handled with messages or fallback values instead of stopping execution. By understanding these concepts, you’ll be able to write more predictable, maintainable, and robust JavaScript code.
