> JSX is not a requirement for using React. Using React without JSX is especially convenient when you don't want to set up compilation in your build environment.

> Each JSX element is just syntactic sugar for calling React.createElement(component, props, ...children). So, anything you can do with JSX can also be done with just plain JavaScript.

Sure. At the bare minimum, you write "manual" `React.createElement()` calls. To simplify or shorten things, you can alias `React.createElement()` to something like `h()`.

There's also a variety of libs to help with that process. We have an existing ES5/Backbone app that's built with Require.js, and we don't have a "compile" step in there. We just added our first couple React+Redux-based features into that codebase, but can't use JSX due to that lack of compilation. I opted to bring in https://github.com/Jador/react-hyperscript-helpers as an alternative to JSX. Not perfect, but it's a suitable alternative given our limitations. There's several other "virtual DOM/hyperscript"-ish packages out there as well.

It's basically just to use the React.createElement API that JSX transpiles to. I say give JSX a chance though.

Might I suggest .dom[0] instead of React if you are planning to use plain JS. It is tiny and has a slightly simpler API which is nice for plain ES6
