splice is not working

When I say "saying = saying.splice(1,2, "slow", "red");" it returns "quick", "brown" rather then replacing those words with "slow", "red".

Hi Stephen,

You don't want to assign the return value of the splice method call back to saying.

splice returns an array of the removed values.

So saying is going to equal `["quick", "brown"] after the assignment.

You only want to call the splice method on the array.

saying.splice(1, 2, "slow", "red");

You could assign the return value to a different variable if you needed to save the removed elements, for example.
