> In May, we rewrote Atom’s text rendering system from scratch, with the goal of making DOM updates after keystrokes as efficient as possible. We made use of the latest DOM technologies and rendering techniques, and built a tiny React-like library called etch that allows us to structure our rendering code cleanly while still allowing for imperative DOM manipulation for maximal performance in certain code paths. The result is that when typing, typical DOM updates now take less than 5 milliseconds: well within the range required for smooth animation and low energy usage.
