Do not use forEach with async-await

TLDR: Use for...of instead of forEach in asynchronous code.

The problem

Array.prototype.forEach is not designed for asynchronous code. (It was not suitable for promises, and it is not suitable for async-await.)

For example, the following forEach loop might not do what it appears to do:

const fs = require('fs')
const {sync: globSync} = require('glob')
const filesize = require('filesize')
const Terser = require('terser')
const options = require(process.env.TERSER_CONFIG || './terserrc.json')

const getSize = (file) => {
  const {size} = fs.statSync(file)
  return filesize(size)
}
