Error when using ES6/7 features

[ilearnio]

I have just installed it, seems t be a great plugin, but it gave me an error right away when I tried to rename a variable:

undefined:1534
    throw new JS_Parse_Error(message, filename, line, col, pos);
    ^

I reduced my code and found out the reason for this error. It seems that the package doesn't support ES6 strings, imports/exports, async/await etc. For example, this piece of code will fail:

import fs from 'fs'

const foo = `bar`
