Can I support all ES5, ES6, ES7 features?

Question

Are there any ways to config a Reactjs project to support all ES5, ES6, ES7 features?

I mean that I can write all the ES5, ES6, ES7 syntaxes.

I am using babel and webpack.

Answer 1

Yes, with the Babel preset-latest. It contains ES6, ES7 and ES8 (async/await).

See the doc to how to install it and how to disable ES8 if you don't need it.

Answer 2

Here you will find more information about setting up ES7 using babel + webpack:
