Typescript is a hyper-set of JavaScript, which means it supports all JavaScript syntax. It's much like a JavaScript-strong-type version, besides, it has some extended syntax, such as Interface/module.Typescript will remove the type and the unique syntax during compile time, generating pure JavaScript.

An introductory tutorial on Typescript+react development based on Nodejs ecological circle
Overview
This tutorial is intended to provide introductory explanations for front-end program development based on the Nodejs NPM ecosystem.
What is Nodejs?
Nodejs is a high-performance JavaScript scripting environment, built on the chrome V8 scripting engine. It is equivalent to extracting the functionality of JavaScript scripts in t
1. What is typescriptTypescript is a free and open source programming language developed by Microsoft. It is a superset of JavaScript and essentially adds optional static types and class-oriented object-oriented programming to the language. Typescript adds support for the features recommended for the upcoming ECMAScript 6 standard.Google's front-end framework angular is based on typescript development.

close to C. This is a bit of a tweak for front-end developers who are accustomed to JavaScript. Since it is an adjustment, it may be a complete adjustment: introduce the concept of strong type to the whole development . There are two types of mainstream frameworks that currently support the introduction of strong types in javascript: Typescript and Flow.js. Typescript is a strongly-typed superset of JavaSc

I've been working on this for TypeScript a while, a giant hard-to-produce language that gives JavaScript language static typing and compilation.The first TypeScript pure project that completely uses refactoring Node.js is on-line and running stably.The second front-and-back project is also being refactored, and the front-end-based webpack TypeScript routines have
versions, and the standardization Committee decided to avoid "web experience fragmentation" caused by incompatible version languages. As a result, all old code works and the transition is smoother, but the problem is that developers complain that the old problems persist for years.What's annoying is that there is currently no JavaScript proxy that fully supports ES6 (whether it's a browser or server environment), so we really use ECMASCRIPT6 developers to translate ECMASCRIPT6 code into ECMASCR
