Plain JavaScript, without build tools?

When I started to look into using Bit, the docs and tutorial go into using compilers, etc, and introduce much complexity up front.

How do we use bit without any build tools?

Suppose I wish to write plain JS for modern browsers, and use native ES Modules.

Can someone give a brief tutorial on how to do this with no compilers or any tooling, just plain JS using Bit only for code distribution?
