Creates a new array with n elements removed from the left.

  • Use Array.prototype.slice() to remove the specified number of elements from the left.
  • Omit the last argument, n, to use a default value of 1.
const drop = (arr, n = 1) => arr.slice(n);
drop([1, 2, 3]); // [2, 3]
drop([1, 2, 3], 2); // [3]
drop([1, 2, 3], 42); // []
