TypeScript Enhances JavaScript Safely
- TypeScript is a typed superset of JavaScript that adds type annotations and optional compilation to earlier JavaScript versions.
- It enables static type checking and improved tool support while remaining fully compatible with existing JavaScript code.
How to Add TypeScript Easily
- To add TypeScript to your existing JavaScript project, install TypeScript and rename .js files to .ts to start type checking.
- Utilize tooling and configuration files like tsconfig.json and integrate with build pipelines as needed for your environment.
Babel Bridges JS Versions
- Babel transpiles modern JavaScript to older versions for browser compatibility, often targeting ES5 for IE11 support.
- This enables using cutting-edge syntax while ensuring code runs in legacy environments, a crucial step in front-end development.
