   Mitata – Benchmarking tooling for JavaScript▲93

   I always had a sweet tooth for how easy it is to use google/benchmark, but when working with js, current libraries didn't feel right and some were not even accurate enough, so I decided to create my own library to make JavaScript benchmarking tooling better. With more free time, I finally implemented all features I wished for in 1.0.0 and made a lightweight C++ single-header version for moments when google/benchmark is too much. Hope this library helps you as much as it does me.

    Hey HN, I'm Alex, founder of Interval [0]. We’re bringing internal tools written like CLIs to the browser to make them more powerful, through a Node.js SDK which attaches them to a hosted dashboard without any frontend code. Large companies have full teams that work on internal dashboards and tooling. Interval brings that infrastructure to anyone.
