Some of the points have already been made, but I'd like to add to the growing number who suggest that many of the 'improvements' are unreadable -> unmaintainable.

Many of us write in multiple languages. I prefer to write code in a style that is recognisable by the majority, not the nuanced minority. In other words, I'd use != every time. And toString(), too.

That said, there are one or two nice examples, so thanks for sharing. For example, this one's good, and much more readable: let outputArray = Array.from(new Set(array));
