Build Cool APIs In Express and TypeScript

Node is a run-time environment that makes it possible to write server-side JavaScript. It has gained widespread adoption since its release in 2011. Writing server-side JavaScript can be challenging as a codebase grows due to the nature of the JavaScript language; dynamic and weak typed.

Developers coming to JavaScript from other languages often complain about its lack of strong static typing, but this is where TypeScript comes into the picture – to bridge this gap.

TypeScript is a typed (optional) super-set of JavaScript that can help with building and managing large-scale JavaScript projects. It can be thought of as JavaScript with additional features like strong static typing, compilation, and object-oriented programming.
