Add Items Using splice()

Hints

Hint 1

  • Using the splice() function, you must remove the first 2 elements from array arr and replace them with DarkSalmon and BlanchedAlmond.
  • Remember the splice function can take up to three parameters.

Example:

arr.splice(0, 1, "Two");
/*  The first two paramemters are the same as they were in the previous challenge. 
    `0` will start the `splice()` function off at index 0.
    The second parameter `1` will remove only 1 variable from the array.
    The final variable "Two" will replace the variable in arr[0].
    Note: The final parameter can take more than 1 arguement.
