## Description
<section id='description'>
Given the array <code>arr</code>, iterate through and remove each element starting from the first element (the 0 index) until the function <code>func</code> returns <code>true</code> when the iterated element is passed through it.
Then return the rest of the array once the condition is satisfied, otherwise, <code>arr</code> should be returned as an empty array.
Remember to use <a href='https://www.freecodecamp.org/forum/t/how-to-get-help-when-you-are-stuck-coding/19514' target='_blank'>Read-Search-Ask</a> if you get stuck. Try to pair program. Write your own code.

```yml
tests:
  - text: <code>dropElements([1, 2, 3, 4], function(n) {return n >= 3;})</code> should return <code>[3, 4]</code>.

  - text: <code>dropElements([0, 1, 0, 1], function(n) {return n === 1;})</code> should return <code>[1, 0, 1]</code>.
    testString: assert.deepEqual(dropElements([0, 1, 0, 1], function(n) {return n === 1;}), [1, 0, 1]);
  - text: <code>dropElements([1, 2, 3], function(n) {return n > 0;})</code> should return <code>[1, 2, 3]</code>.
    testString: assert.deepEqual(dropElements([1, 2, 3], function(n) {return n > 0;}), [1, 2, 3]);
  - text: <code>dropElements([1, 2, 3, 4], function(n) {return n > 5;})</code> should return <code>[]</code>.

```js
function dropElements(arr, func) {
  // Drop them elements.
  while (arr.length && !func(arr[0])) {
    arr.shift();
  }
  return arr;
}
```
