TypeScript Assert Functions #typescript #programming #engineering #javascript #tutorial

In this quick video, we explore the power of assert functions in TypeScript. Assert functions are invaluable tools for enhancing the reliability of your code by validating conditions and preventing potential errors. Join us as we delve into the world of assert functions and learn how to use them effectively.

We start by introducing a simple TypeScript function that calculates the square root of a number. However, we quickly discover the need to handle invalid inputs, such as negative numbers. That's where assert functions come to the rescue!

With code snippets and a step-by-step explanation, we demonstrate how to implement an assert function that checks a condition and throws an error with a custom message if it fails. By integrating this assert function into our square root calculation, we ensure that only non-negative numbers are accepted, minimizing the risk of errors.

Whether you're a beginner or an experienced TypeScript developer, assert functions are an essential addition to your toolkit. They provide an early detection mechanism for potential issues and contribute to writing more robust and reliable code.

Watch this video now to learn how to leverage assert functions in TypeScript and improve the quality of your projects. Enhance your coding skills and join us on this journey to write safer code!

Your shorts are epic, keep going please

How is this better than simply performing the check and throw inside of the function itself, instead of abstracting it to this assert function?

Does this also work for filtering out nullish values?

In tutorials you shouldn't call the function "assert". It's too confusing when the keyword is "asserts". It's also obviously a poorly named function.

It makes the code harder to follow in a short. But the video is good other than that.
