TypeScript is a superset of JavaScript, yet browsers and other platforms don't recognize it, nor are they able to execute it. For that purpose, TypeScript is processed by the TypeScript compiler, which transpiles your TypeScript code to JavaScript. Then, you can run the transpiled code basically everywhere JavaScript is supported.
The tsc is available as an npm package that you can install globally. Open your favorite terminal and install it using the following command:
npm install -g typescriptAfterwards, you can use the command tsc to execute the tsc:
TypeScript files have a .ts file extension; this is where you write your TypeScript code. When needed, you use the TypeScript compiler to transpile your TypeScript code, which creates the JavaScript implementation of the code; you do that by executing the following command:
tsc <typescript_filename>
