Echo JS 0.11.0

I also like the library. The only thing that I don't like is that it needs Webpack/Babel to be built. Changing 2 lines of code would make it ES5 compatible out of the box.

If you're pulling from npm, you should be getting the already built version.  And to use it, you can use a regular function expression instead of the fat-arrow syntax.  I'm not sure what requirement you're referring to.

The project itself is using wp/babel, but the output is usable, and what's in npm that you can use without it.  All the dependencies in package.json are dev dependencies, if you do a prod install, it won't even download them.

That said, I can't think if the last project I started that wasn't using babel.

Ah I wasn't aware that the built version was published on npm. Thanks for pointing that out. I downloaded the library and ran the build process myself. NPM install pulled in about 100MB dependencies. This seemed really overkill for a 30 LOC mini library.

IMHO the majority of the web does not use stuff like Webpack / Babel (yet). Just look at all those Wordpress, Joomla installations and apps older than 2 years. So being able to pull in a frontend library via script-tag is still a must in my opinion.

Yeah, though npm is really an ecosystem built around cjs modules (though some moving towards ES6), and a lot of code now being written in ES6.  In some cases, it's hard to decide to leave the ./src directory or not, in addition to ./dist for the potential of tree shaking etc.
