What is the difference between polyfills and transpilation?

What is the difference between polyfills and transpilation?

Polyfills are scripts that provide modern functionality on older browsers, while transpilation converts code from one version to another.

Can you give me an example of a polyfill?

Sure! A common polyfill is the 'Promise' object, which allows asynchronous programming in browsers that don't support it natively.

What about transpilation? How does it work?

Transpilation involves using tools like Babel to convert ES6+ JavaScript code into ES5 code, making it compatible with older browsers.

When should I use polyfills instead of transpilation?

Use polyfills when you need to add specific features to older browsers, and transpilation when you want to write modern code that needs to run in those environments.
