The TypeScript Rap Song

If the astronaut didn't convince you, this rap song certainly will.

Are you facing issues with TypeScript? 😵‍💫

TypeScript is a superset of JavaScript. It can do everything JavaScript does, and even more. But there's a trade-off: it gets more complex and you'll need to learn new things like Generics, Abstract Classes and Ambient Modules.

Because TypeScript needs to work wherever JavaScript works, it has to be compiled before it can run. This processing is why you have to install the TypeScript compiler (tsc). The compiler checks your code while you're working on it and tells you about any mistakes. There are hundreds of different mistakes you can make.

The good news is that you've found this website. It's a helpful guide that lists the most common TypeScript errors and explains how to fix them. There's also a glossary that defines tricky words in just a sentence or two.
