Do you wanna PR for ES2015 modules?

[tunnckoCore]

It is very much used everywhere and by me too. So I can PR to create it both CJS and ES2015 compatible. So later when some modern bundlers like Webpack and Rollup can resolve es2015 module.

The simplest thing is just pass jsnext:main: path/to/file.with.es2015.exports.js and the current main will remain the same.

Rollup and Webpack2 understands jsnext:main and module fields, so when they do bundling they will resolve that files, not the CJS main.

Specifically, Rollup has plugin to convert CJS to ES2015 modules, but it won't do the tree-shaking magic, so it will be possible to duplicate exact that extend-shallow code multiple times if found multiple times.

It would be just

import isObject from 'is-extendable';

export default function extend(o/*, objects*/) {
  if (!isObject(o)) { o = {}; }

  // ... code
};

also converting is-extendable to es2015 would be good too.

edit: haha, i jumped to that train a bit and it's very inspiring and funny :laughing: :rocket:

Why? There is no advantage in doing this. It would only make it less compatible and slower.

[tunnckoCore]

Less compatible with what? Slower? Why?

The current code won't be even touched. We just need one more file with just ES2015 modules definitions and one more field in package.json which will help ES2015 aware bundlers to do their job better.

The advantage is lower duplication of code (in the bundle) and smaller install times for the user. And all that without any costs (except that npm package will have one more file in it).

this is what you should start the issue with next time lol. sure, that's fine with me

[tunnckoCore]

haha

I thought that will be enough:

But yea.. I'm bot. :dagger:

Okey, i'll send a pr this night

[jonschlinkert]

sorry, lol. Sometimes I have to skim issues and I missed the important part of your comments.
