ReactDOM is the component of react that is responsible for rendering components to the DOM. When digging into profiles, a large number of our performance bugs, especially bugs involving responsiveness, have ReactDOM code as the hottest JS code.

Examples: Bug 1702926, bug 1701956, bug 1363383, bug 1680195 (and more generally everything that happens on Facebook), bug 1692914, bug 1686592.

These cases also generally spend a lot of time in megamorphic property lookup. We're hopeful that Jan's ReShape work in bug 1704430 will improve that.

We should look for additional performance improvements in ReactDOM, because so many important websites depend on it. This metabug is for tracking that work.
