I was solving a problem and saw when I used Array.map the execution was lagging a bit. And thought to switch to using for...loop, as I was not doing any complicated calculation within map callback.
This is the sample benchmark data I used
6,1,4,5,3,9,0,1,9,5,1,8,6,7,0,5,5,4,4
And I did not do anything fancy, just pushed it to an array, similar to map where is returns us a new array.
Compared it using JS Perf and saw that for..loop is ~25 times faster than map.
I would not be switching to for..loop because of this, a good to know when there is a slow down in the application.
