Tell us what’s happening:
my code bring the right results. But freecodecamp is not accepting. whats wrong ?

Your code so far


function dropElements(arr, func) {
  // Drop them elements.
  var lst = [];
  for (let i = 0; i < arr.length; i++) {
    
if (func(arr[i]) === true) {
  lst.push(arr.splice(i)); 

}
  }
  return lst;
}

var result = dropElements([1, 2, 3, 9, 2], function(n) {return n > 2;});
console.log(result);

Actually, it is not returning the correct results.

For example, for the first test dropElements([1, 2, 3, 4], function(n) {return n >= 3;}), your function returns [ [ 3, 4 ] ], but the correct answer is [ 3, 4 ]. You are returning a multi-dimensional array instead of a one-dimensional array. Remember that arr.splice(i) is still an array, so you are pushing an array into an array instead of the values of the array into an array.

I am wondering how i can know this next time. Because on the console it will bring it as [ 3, 4 ] instead of [ [ 3, 4 ] ] which you just showed me.

I see, you are extracting correct result and building new array, but it actually asks rest array after condition is true, suppose dropElements([1, 2, 3, 9, 2], function(n) {return n > 2;}); Here arr[2] > 2, so here condition is true, and from now, rest array is [3,9,2], But I think, there may be a some mistakes, it checks only first element and accepts the output.
