Transpile to es5 to support older devices about clipboard-copy HOT 4 OPEN

I think that transpiling code is something that must be done by the end user in this case, since there is no way for us to know exactly which browsers/environments they are targeting. It's my opinion that it's better for all code on npm to use the latest language features, and then someone building a website can configure their build process to transpile accordingly...

Usual babel setup only transpiles project's source code and doesn't touch node_modules. Most of the libraries target ES5 as a base case and sometimes they also provide additional target like esnext.
I understand what you are saying, but in my opinion it is unexpected of library not to support ES5.

Transpiling async/await syntax comes with a very large overhead, which will probably balloon the size of this library way over the 508 B gzipped that this library currently comes in at. It would be interesting to test and see the difference...

It seems like a bad approach that all newer browsers should pay the price of running older code, even on websites that aren't even supporting older browsers?

I thought of something like this https://github.com/xobotyi/scrollbar-width/blob/master/package.json#L33
Here you have 3 targets, one of them "main" is es5.
