Load mathjs in a browser module (ES import)

Currently it looks like it’s not possible to use mathjs in a browser module like:

<script type="module">
  import { create, all } from 'mathjs'
</script>

I think the existing bundles in dist do not have the right exports to be consumed as an ES module.

What should work (but doesn’t) is loading like:

import { create, all} from 'mathjs/main/es/index.js'

I think the reason is that many import paths in the code are missing the explicit “*.js” extension, which is the normal way to go in nodejs and webpack environments, but not in browser ES environments which require a real path to a file.

It’s quite complicated :S

mathjs has no global state, you have to create your own mathjs instance with for example create(all, config), and in this instance there is state like the config. It may be possible that some difficulties arise because we integrate for example Complex and BigNumber, I’m not entirely true if mathjs adds methods to these libraries.

I think you’re correct about the lack of file extension; browser environments expect the full path and filename. Is there a way you could tell Gulp to add the .js to imports when it created the files?
