Instructions

Create three functions that receive an array and a function each:

  • every that returns true if every element of the array respects the condition of the received function and false otherwise.
  • some that returns true if at least one element of the array respects the condition of the received function and false otherwise.
  • none that returns true if none of the elements of the array respects the condition of the received function and false otherwise.

The use of [].every and [].some is forbidden for this exercise.
