So for the past couple days, I’ve been deep into TypeScript, which is a super-set of the Javascript language that adds optional typing, classes, and module support in addition to standard Javascript.
I’d recently been checking out Dart, from Google, as a way to write Javascript-intensive applications in a way that multiple humans can write code and eliminate a lot of the errors that come along with the dynamic typing. See, dynamic typing is powerful. You can do a whole lot of cool things when you can do anything you want. The issue comes when the app gets so big you can’t keep everything in your head, or you have someone else working with you. Then, you need a way to know what methods are accepting and returning without having to crack open that method and read the code (that’s why we HAVE classes so we can write something once, and then forget about the specifics of it and only care about the passed argument and return value). That’s all you need to get you going!

Welcome to TypeScript. TypeScript. TypeScript is a strict superset of JavaScript, so any existing JavaScript programs are also valid TypeScript programs.
TypeScript is designed for development of large applications and compiles down to JavaScript.[5] TypeScript supports header files which can contain type information of existing JavaScript libraries, enabling other programs to use objects defined in the header files as if they were strongly typed TypeScript objects. There are third-party header files for popular libraries like jQuery, MongoDB, Node.js, and D3.js.[6] Background[edit] TypeScript originates from the need to develop large-scale JavaScript applications.
Internally at Microsoft the challenges with dealing with complex JavaScript code led to demand for custom tooling to ease the writing of components in the language.[8] Microsoft has stated that they did not have the intention of making something that could break compatibility with the standard and its cross-platform support. Language features[edit] Classes[edit] Why does TypeScript have to be the answer to anything?
