What makes me skeptical is reading > I just don’t think we’ve exhausted all the possibilities of making JavaScript tools faster and then > Sometimes I look at truly perf-focused JavaScript, such as the recent improvements to the Chromium DevTools using mind-blowing techniques like using Uint8Arrays as bit vectors, and I feel that we’ve barely scratched the surface. Bit vectors are trivial? I think the author is too ignorant about those "faster languages". Sure, maybe you can optimize javascript code, but the space of optimizations is only a small subset of what is possible in those other languages (e.g. control over allocations, struct layout, SIMD, ...)
