    Mitata – Benchmarking tooling for JavaScript▲93

    I always had a sweet tooth for how easy it is to use google&#x2F;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&#x2F;benchmark is too much. Hope this library helps you as much as it does me.
