it's nice when mine matches the top answer

What I did............

pure code

same sol

hell no! this func called sortByLength.

If you mean like callback function - yes it is anonymous

And mine! ;)

Amazing

It ensures case-insensitivity:

"Alligator" != "alligator"

Forcing the animal to lower case means it will always match properly.

Thing is you should be aware if you CAN or CAN'T change the original array. As a good practice we always copy the original to another before doing any changes, but there will always be situations where you don't need to do that.

identical to my solution ! :D

does it anonymous function?

Good one man!

Ok, thanks.
