Problem Explanation:

Return the remaining elements of an array after chopping off n elements from the head.

For example: slasher([1, 2, 3], 2); must return [3]

Analysis:

We need only the remaining part of an array, so we can just remove what we don't.

Understanding slicing:

.slice() allows to get only what you want from an array.

Understanding the splice:

If you want the tail of a snake remove the head first. The .splice() method changes the content of an array by removing existing elements and/or adding new elements. This can be handy. Get an array, remove the first part and return the remaining.

Spoiler Alert!

Solution ahead!

Code Solution:

function slasher(arr, howMany) {
  // remove the head
  arr.splice(0,howMany);
  //return the remaining or the tail  \__/(**)-<
  return arr;
}
slasher([1, 2, 3], 2);

Code Solution 2:

function slasher(arr, howMany) {

  //Return string after the amount chopped off.
  return arr.slice(howMany);

}
