问题 I have just finished writing "version 0" of my first (toy) transpiler. It works. It turns a string of "pseudo JavaScript" (JavaScript with an additional feature) into a string of runnable JavaScript. Now, I want to improve it. The work area possibly most interesting for other SO users is this: The compiled code (i.e., output of my transpiler) does not heed a coding style recommendation as given in an accepted answer to some earlier SO question. If I would have at my hands a second transpiler

问题 I'm new to babel and trying to transpile my es6 code to work with IE11. But when I run the code in IE11 I get js errors about my forEach code. From what I've read I needed to add the preset @babel/preset-env . I added that to my config file so I'm not sure why it's not transpiling those forEach calls. const path = require('path'); module.exports = { entry: { setupForm: "./Scripts/es6/setupForm.js", prelimForm: "./Scripts/es6/prelimForm.js" }, output: { filename: '[name].js', path: path
