Let's start with a simple Hello World Node.js example. tsc -versionĪnother option is to install the TypeScript compiler locally in your project ( npm install -save-dev typescript) and has the benefit of avoiding possible interactions with other TypeScript projects you may have. You can test your install by checking the version. If you have npm installed, you can install TypeScript globally ( -g) on your computer by: npm install -g typescript The easiest way to install TypeScript is through npm, the Node.js Package Manager. You will need to install the TypeScript compiler either globally or in your workspace to transpile TypeScript source code to JavaScript ( tsc HelloWorld.ts). Visual Studio Code includes TypeScript language support but does not include the TypeScript compiler, tsc. It offers classes, modules, and interfaces to help you build robust components.
TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.
