What is the difference between transpiling and polyfills?

Transpiling is the process of converting code from one version of a language to another, while polyfills are scripts that provide functionality that is not natively supported in certain environments.

Can you give me an example of when to use a polyfill?

Sure! If you're using modern JavaScript features like Promise in an older browser that doesn't support it, you would use a polyfill to add that functionality.

And when would I need to transpile my code?

You would transpile your code if you're using ES6+ features but need to support older browsers that only understand ES5.

Are there any tools that can help with both transpiling and polyfills?

Yes! Tools like Babel can transpile your code, and you can use polyfill libraries like core-js to add necessary polyfills.
