TypeScript

TypeScript is an open-source programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript, and adds optional static typing to the language.

TypeScript is designed for development of large applications and transcompiles to JavaScript. As TypeScript is a superset of JavaScript, existing JavaScript programs are also valid TypeScript programs. TypeScript may be used to develop JavaScript applications for both client-side and server-side.

To get started with TypeScript installation, you need to first install Node.js in your system.

Node.js

Install Node.js https://nodejs.org/en/download/ https://en.wikipedia.org/wiki/Node.js

Node.js is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code outside of a browser. Historically, JavaScript was used primarily for client-side scripting, in which scripts written in JavaScript are embedded in a webpage's HTML and run client-side by a JavaScript engine in the user's web browser. Node.js lets developers use JavaScript to write Command Line tools and for server-side scripting-running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "JavaScript everywhere" paradigm, unifying web application development around a single programming language, rather than different languages for server side and client side scripts.

Installation

https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs

Alternatively, for Node.js 10:

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs

Optional: Install build tools. To compile and install native addons from npm, you may also need to install build tools:

sudo apt-get install -y build-essential

También hay que instalar ts-node:

sudo npm install -g ts-node

TypeScript Installation

As you have already installed Node, it's time to install the TypeScript Package using the Node Package Manager (NPM).

npm install -g typescript

Git Bash in Windows

Si estamos en Windows, tenemos que instalar Git Bash in Windows; que es tan sólo un terminal Bash en Windows.
