Why TypeScript?

Before we start with Why, we should probably look at What is TypeScript?

TypeScript is a programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript and adds optional static typing to the language. TypeScript is designed for the development of large applications and transcompiles to JavaScript

I was gonna say that I think "steroids" are a bad analogy. But after I actually bothered to read up on them, I think the analogy is perfect.

Steroids just make you look tougher without making you tough. From my experience using TS for a couple of…
