#Performance of different #JS engines about 10 years ago, comparing #QuickJS to #Duktape, V8, plus two other lightweight JS implementations, #JerryScript and #MuJS, and apparently things called Hermes and XS (#Moddable?). Taking V8 as the baseline, roughly, V8 --jitless is 22× slower, QuickJS and Hermes are 37× slower, Duktape is 88× slower, XS is 56× slower, MuJS is 260× slower, and JerryScript failed to run most of the tests.
