Tell us what’s happening:

my code works for most cases, yet only one passes. what is wrong?

Your code so far


function dropElements(arr, func) {
// Drop them elements.
if(func(arr[0])) {
  return arr;
} else {
  arr.shift();
  dropElements(arr,func);
}
}

dropElements([1, 2, 3, 7, 4], function(n) {return n > 3;})
//should return '[7, 4]' and it does, yet i don't pass

Your else condition doesn’t return anything.

it’s not supposed to.
it’s a recursive loop that drops the first element in the array, and starts the function again

UPDATE: i finished the code, it individually passes all the tests in the console, but the GUI still doesn’t let me pass

function dropElements(arr, func) {
  // Drop them elements.
  if(func(arr[0]) || arr.length === 0) {
    console.log(arr);
    return arr;
  } else {
    arr.shift();
    dropElements(arr,func);
  }
}

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

then what do you do with the value returned from the call inside the else?

remember that if a function doesn’t return anything, it returns undefined by default. The else statement doesn’t contain a return, so if the else run, nothing is returned
