How to make Ecmascript 6 compatible with IE?

Question

JavaScript

Good health dear toasters! There is an average project written using React and the latest syntaxes of this Javascript of yours. The problem is that all this goodness absolutely does not work on IE11. You need to get her support. Overtook through Babel with es2015, alas, without the original - the syntax changes, but with some methods the problem is all sorts of Array.find and so on. What can you advise in this case?
