Why wait for the jQuery part to use .each(), when plain Javascript also has forEach()?

Writing a for loop is so much more abstract than forEach.

This is most likely due to the dreaded Internet Explorer 8. The pure JavaScript .forEach() method was not introduced to IE until version 9, so for backwards compatibility it would be better to rely on jQuery.

The other argument I have found is that in some performance tests, $.each() actually seems to perform better than Array.forEach(), though I have read sources that claim this is no longer an issue. I will say that when I run the following performance test on MY machine, using Chrome/OS X, .each seems slightly faster.

forEach vs. jQuery .each vs. for vs for..in
