TypeScript is a superset of JavaScript that adds support for static types. This enables early error detection, thereby enhancing code quality and maintainability.

These are some of the benefits of using TypeScript:

  • Static type checking reduces the chance for runtime errors.
  • Enables more productive coding by providing meaningful auto-completions and alerts when something is wrong.
  • It provides implicit documentation on how to use functions, React components, or other libraries. This makes collaborating with other engineers on the same project much easier.

The aim of this guide is to help you learn and apply best practices to fully leverage TypeScript's capabilities. If you write high-quality TypeScript code and follow some of these guidelines, you'll be able to maintain the long-term health of your projects.

We won't be covering any of the basics here, so if you'd like an intro, you can check out the official TypeScript documentation.
