Introduction and installation and commissioning of Typescript

what is typescript.

Typescript is a superset of ES6, and all ES6 code is fully valid and can be compiled typescript.

The current version of JavaScript is actually ECMASCRIPT5 (ES5), and the next-generation JS standard is ES6. If you want to learn more ES6 knowledge, you can go to Ruan a Feng teacher's github up to find, which has a detailed use case introduction.

If you have the financial strength, I hope you can buy a Nanyi teacher's "ES 6 Standard Primer", an open source book is not as easy as we think. installation

For now, there are two ways to install Typescript: through Node.js npm

If you have not installed Node.js, this article, "Creating a ANGULAR2 project in Windows environment" begins with a show of how to change the operation. directives

NPM install-g typescript

If you have configured the CNPM, then the domestic students I suggest using Taobao mirror.

CNPM install-g typescript is installed via software

Visual Studio 2017 and Visual Studio 2015 Update 3 and Webstorm all already contain typescript by default. If you are using Sublime, there is a plugin installed typescript-sublime-plugin If you are using atom, there is a plugin atom-typescript if you are using Eclipse, This has the install plugin Eclipse-typescript

I am currently using the Desert poor autumn teacher recommended Vscode to write TS file, with the node.js really good use. about Debugging

Because TS files need to be compiled into a JS file, if it is simply learning and testing, then the configuration of debugging is not so important.

We can use a gadget on node--tsun, he will help us debug the configuration file, so that we can more quickly get started TS.

To install using NPM:

NPM Install-g Tsun

Use CNPM:

CNPM Install-g Tsun

After the installation is successful, you can start it:

If the following information appears, you have successfully installed
