[TypeScript](https://www.typescriptlang.org/) is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the [playground](https://www.typescriptlang.org/play/), and stay up to date via [our blog](https://blogs.msdn.microsoft.com/typescript) and [Twitter account](https://twitter.com/typescript).
Find others who are using TypeScript at [our community page](https://www.typescriptlang.org/community/).
## Installing
For the latest stable version:
```bash
npm install -g typescript

## Building
In order to build the TypeScript compiler, ensure that you have [Git](https://git-scm.com/downloads) and [Node.js](https://nodejs.org/) installed.
Clone a copy of the repo:
```bash
git clone https://github.com/microsoft/TypeScript.git
```
Change to the TypeScript directory:
```bash
cd TypeScript
```
Install [Gulp](https://gulpjs.com/) tools and dev dependencies:
```bash
npm install -g gulp
npm ci
```
Use one of the following to build and test:
```
gulp local # Build the compiler into built/local.
gulp clean # Delete the built compiler.
gulp LKG # Replace the last known good with the built one.
# Bootstrapping step to be executed when the built compiler reaches a stable state.
gulp tests # Build the test infrastructure using the built compiler.
gulp runtests # Run tests using the built compiler and test infrastructure.
# You can override the specific suite runner used or specify a test for this command.
# Use --tests= for a specific test and/or --runner= for a specific suite.
# Valid runners include conformance, compiler, fourslash, project, user, and docker
# The user and docker runners are extended test suite runners - the user runner
# works on disk in the tests/cases/user directory, while the docker runner works in containers.
# You'll need to have the docker executable in your system path for the docker runner to work.
gulp runtests-parallel # Like runtests, but split across multiple threads. Uses a number of threads equal to the system
# core count by default. Use --workers= to adjust this.
gulp baseline-accept # This replaces the baseline test results with the results obtained from gulp runtests.
gulp lint # Runs eslint on the TypeScript source.
gulp help # List the above commands.
```
## Usage
```bash
node built/local/tsc.js hello.ts
```
