Introduction

The TypeScript compiler type checks our code as well as transpiling it to JavaScript. In this module, we are going to learn how to control both these processes.

We may want Babel to do the transpilation rather than TypeScript. We may only want TypeScript to compile code in a certain folder. We may want to relax the type checking rules because we are migrating code from JavaScript. We will learn how to do all these things in this module.

In this module we will cover:

• Installing and running the compiler
• Compiling specific files
• Controlling transpilation
• Emitting source maps
• Controlling type checking against standard libraries
• Controlling type checking strictness
• Controlling code quality options
