One thing that I see more often recently is that folks find out about the never type, and start using it more often, especially trying to model error handling. But more often than not, they don’t use it properly or overlook some fundamental features of never. This can lead to faulty code that might act up in production, so I want to clear doubts and misconceptions, and show you what you can really do with never.| fettblog.eu

When you are coming from languages like Java, C++, or C#, you are used to doing your error handling by throwing exceptions. And subsequently, catching them in a cascade of catch clauses. There are arguably better ways to do error handling, but this one has been around for ages and given history and influences, has also found its way into JavaScript.| fettblog.eu

One way to think about TypeScript is as a thin layer around JavaScript that adds type annotations. Type annotations that make sure you don’t make any mistakes. The TypeScript team worked hard on making sure that type checking also works with regular JavaScript files. TypeScript’s compiler (tsc) as well as language support in editors like VSCode give you a great developer experience without any compilation step. Let’s see how.| fettblog.eu
