Remove empty strings from array while keeping record Without Loop?

This question was asked here:
Remove empty strings from array while keeping record of indexes with non empty strings

If you'd notice the given as @Baz layed it out;

"I", "am", "", "still", "here", "", "man"

"and from this I wish to produce the following two arrays:"

"I", "am", "still", "here", "man"

All the Answers to this question referred to a form of looping.

My question: Is there a possibility to remove all
es with
without any looping? ... is there any other alternative apart from iterating the array?

May be some
or some
that we are not aware of?

All answers or suggestions are highly appreciated.

var arr = ["I", "am", "", "still", "here", "", "man"]
// arr = ["I", "am", "", "still", "here", "", "man"]
arr = arr.filter(Boolean)
// arr = ["I", "am", "still", "here", "man"]

filter documentation

// arr = ["I", "am", "", "still", "here", "", "man"]
arr = arr.filter(v=>v!='');
// arr = ["I", "am", "still", "here", "man"]
