TypeScript Basics 4 - TypeScript versus JavaScript

Understand how TypeScript compares with JavaScript. TypeScript is said to be a 'superset' of the JavaScript language. In this video, we'll learn why.

Learn about the basics of TypeScript. Understand how types work, how to use arrays and tuples, how to declare classes and interfaces. Understand concepts of type erasure, duck typing, enums, generics and modules. Create a development workflow and configure the TypeScript compiler to your needs. And watch as I build an end-to-end TypeScript application from scratch.

Hi, I understand javaScript has implemented new features that are not compatible across all the browsers, but you have Babel which converts new JS code and translate it to ES5 code that is understood by browsers.

Even typescript is not supported by the browsers, you need to transfile in order the browsers could able to read so it’s the same thing.
