Drop it (can't past 1 test, help please)

Tell us what’s happening:

Hey. I dont know why my code doesnt work. It’s supposed to shift a value from an array if func is false, but when the biggest value in an array is lower than the value for which function is true it doesnt shift all the the values from the array? it just returns [3,4] instead of []. Help please

Your code so far

function dropElements(arr, func) {
  for (var i = 0; i < arr.length; i++) {
    if (!func(arr[0])) {                       // if func is false
      arr.shift();                                // shift the value from an array
    } else {
     console.log("func = true")        // if its true do nothing, and the value stays

  return arr;                                  // returns [3,4] except of an empty array []  Why?

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

This problem ( basically the same) is being posted few days ago^^

var result = arr.length;
  for (var i = 0; i < result; i++) {
    if (!func(arr[0])) {                     
    } else {
