designed ones!When talking about performance, we typically think about the function logic. We’ll see that a well designed function API can have an even larger impact.How will we compare performance? ● they might be, and often are, totally irrelevant to speed. 17 Credit to Khalil Estell: Firefox function distribution 157946 functions above (127B) 167404 functions below (127B)Understanding how machine problems?
