Is it faster to use the native forEach or just loop with for?
Types of methods for test:
- forEach
- for loop, simple
- for loop, cached length
- for loop, reverse
- for loop, cached length, callback
- $.each
- for … in
- for loop, reverse decrement
- other crazy loops
Is it faster to use the native forEach or just loop with for?
Obviously, the most faster loop is for with cashed array length. But in my case it was ordinary for loop :)
Also I was confused that Array.forEach method is slowest more than 89% from classic for loop…
