splice() method can be used to add multiple new items to an array.
This method also allows us to specify the position of the new elements and also if any elements should be removed.
Let's go through an example to better illustrate this concept.
Say we wanted to add two fruits (Lemon and Banana) after the second element in our array (which is Orange).
To do this we can type in the following
fruits.splice(2, 0, "Lemon", "Kiwi");
The 2 indicates that we want the new element to start with an index number of 2. The 0 indicates that we do not want to remove any of the other elements in our array.
