JavaScript is an easy to learn programming language. It’s easy to write programs that run and does something. However, it’s hard to account for all the uses cases and write robust JavaScript code.
In this article, we’ll look at how to add polyfills and language features to our app to add features that aren’t built into the browsers we’re targeting.
Polyfills are important for making our client-side JavaScript code robust. Polyfills are scripts that add features that browsers may not otherwise support.
It implements particular JavaScript APIs that browsers may not support yet. Part of the JavaScript standard library that isn’t available in the browser that we’re targeting also need polyfills.
They’re just libraries that we add just like any other library. For instance, some API like the Fetch API or the Network Information API may not be available yet.
