The ".fasterMap()" method is almost twice as fast as the ".map()" ten. Usage is the same.

var arr = [1, 4, 3, 3, 9, 11]
arr.fastermap(x => x > 5)

return 9, 11

".remove()" method

var arr = [1, 4, 3, 3, 9, 11]
arr.remove(3)

return [1, 4, 3, 9, 11]

".removeAll()" method

var arr = [1, 4, 3, 3, 9, 11]
arr.removeAll(3)
