CAN WE MAKE REACT FASTER USING THE REACT COMPILER?

Summary from the TLDR Dev newsletter

React Compiler uses cache slots and tracks values that change together to avoid unnecessary work. In a 2,000-row microbenchmark, inlining alone slowed rendering from 444 ms to 1,038 ms by removing per-row caches, while adding block DOM updates cut it to 164 ms. These prototypes illustrate optimization opportunities, with workload and memory tradeoffs still to evaluate.
