Approaching React performance with Halogen

Just be careful that checking equality with eq isn’t even more costly than just re-rendering! You can also pass a custom equality function that just checks on things like whether the UUID is the same to save on performance.

This! That todo app does it more as a demonstration than out of need. Usually it’s just faster (and the code is simpler) to naively re-render until you experience a problem.
