javascript - Looking for answers, developing with ES6, how to use ordinary JS plug-ins

Question

Yesterday I used gulp's babel browserify to build and develop using ES6 (non-react, vue),

There is a problem with plug-in introduction. Most js plug-ins on the market are not developed using ES6 syntax. So how can they be used directly when writing code in ES6?

If you need to modify the plug-in, how to modify it?

Answer 1

Can be used directly, es6 is backward compatible.
