This is a duplicate of #697. Optional catch binding is supported as per the Compatibility section in the readme. You can use Babel to transpile dependencies to support older engines.

Hi! Thanks for taking the time to contribute!

Because we treat pull requests as our backlog, we close duplicates to focus our work and not have to touch the same chunk of code for the same reason multiple times. This is also why we may mark something as duplicate that isn’t an exact duplicate but is closely related.

Thanks,

So this tool suggests using Babel or older engines, what was the original intention behind creating this tool?

This library, react-markdown converts markdown into react.
And targets modern evergreen browsers by default.
It can also be used with legacy browsers, using babel to transpired and polyfill.

The modern browser first approach is done because we don't want to force millions of people to download legacy syntax and polyfills they don't need.

In the cases legacy support is needed, Babel or SWC can quickly and efficiently add only the syntax and polyfills that you and your specific browser matrix need.
