Understanding Vue's reactivity system by building one
summary
Explains JavaScript reactivity by starting with a non-reactive render function, then adding reactivity using ES getters/setters to collect dependencies and build a Vue-like reactivity system. Covers problems that system solves and the issues it introduces, and describes how Vue’s newer reactivity uses ES Proxies as a solution. Includes a brief ES getters/setters crash course.
