TypeScript Tutorials - 01 TypeScript Introduction
Hi!
My name is Ashman Malhotra.
Thank you for giving me opportunity to welcome you in my brand new Tutorials series on TypeScript Programming Tutorials.
TypeScript is designed by Anders Hejlsberg, who designed C# Language at Microsoft.
TypeScript is open source and is available for free.
The TypeScript syntax is based on ECMAScript 4 and ECMAScript 6 Proposals.
TypeScript is a superset of JavaScript that compiles to JavaScript. Finally, it is the JavaScript code that you will execute on your browser.
While writing TypeScript code, we will still write JavaScript code augmented by class-based oop of ECMAScript 6 and structural type system of ECMAScript 4.
Once the code is written, it will be compiled to produce regular JavaScript code, which will execute on all existing browsers.
Now, you may have question – if it JavaScript code that finally executes on browsers, why you should learn TypeScript and use TypeScript over JavaScript?
Till date, whatever JavaScript code you have written is a valid JavaScript code. Earlier, JavaScript was written for client side application but with the invent of NodeJS, JavaScript is also used at server side.
The problem is when JavaScript code grows to 100 and thousand lines of codes or when it grows to plenty of files; it becomes Messier, difficult to maintain and reuse the code. It also becomes difficult to debug the code at some or other point of time.
Originally, JavaScript gives you all those features that will make your life easy to manage, debug and scale your applications with lot of advance features. So, you will focus on TypeScript without worrying much about the JavaScript.
Therefore, in this course, I will discuss all important aspects of the TypeScript language so that you could have proper understanding of the TypeScript Language.
