// Create a method none? (JS none) that accepts an array and a block (JS: a function), and returns true if the block (/function) returns true for none of the items in the array. An empty list should return true.


function none(arr, fun){
    for(let i = 0; i < arr.length; i++) {
      if(fun(arr[i])) {return false}
    }
      return true
    }
