Wanted to say this is complex solution, but it is probably one of more performant out there. I see others doing sort (which is expensive) - also me, but also stringifying array later which is even worse and more expensive operation.

sounds easy enough to test, I'd be interested in seeing any results

It should be faster than regex solution

One of the least performant solutions but still nice looking :)

Nah, it's a perfectly normal "best solution".

Dont repeat yourself :)

This one is probably shortest but it's really expensive for computer as we are building array & string on each iteration.

same issue here :( seems like it was issue with modificating array with reverse function

damn :) true... it just evokes that it want's to go through all of them.

The every method executes the provided callback function once for each element present in the array until it finds one where callback returns a falsy value. If such an element is found, the every method immediately returns false.

every() or some() also don't have to go through all the elements, they will stop at the first element which do not fit ;-)
