Note: Array.prototype.at() is available now

[]["at"] ([][(![]+[])[+!![]]+(!![]+[])[+[]]]) may replace []["filter"] or []["fill"] ([][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(![]+[])[!+[]+!+[]]]) to get a Function and it should work with latest browser versions except Safari as of now.

(This note is for golfing but not for compatibility though)
