Every developer has, I have at least, been in the situation, that I needed some quite performant code, but didn't know which piece of code is faster - and how does one even test this? ? Well, this is not an issue any longer! https://hasty.dev has come to the rescue! Simply input some global data to test from, then a few pieces of different code, that essentially does the same thing. Press `Run` and boom https://hasty.dev is now testing the code, and will return in three (3) seconds. ? It's that easy! ? To make the list complete, you can even share links of your performance test code and send it directly to other users ?
