Isn't that a lot like hyperscript? Maybe I like this or mercury or I one of the other varieties better for one reason or another. Is ReactDOM the best fit for everyone?

I've never used HyperScript, and I made no claims about anything being the ONE TRUE TOOL. I suggested that yladiz's recommendation would fit your described preferences better without injecting JSX.
