Drop the elements of an array (first argument), starting from the front, until the predicate (second argument) returns true.

drop.js

function drop(arr, func) {
  // Drop them elements.
  var length = arr.length;
 for(i=0;i<=length;i++){
   if(func(arr[0])){
     return arr;
   }
   console.log(arr);
   arr.shift();
   if(arr.length === 0){
     return [];
   }
 }
}

drop([1, 2, 3, 4], function(n) {return n > 5; });
