Deleting items from arrays

Now that we know how to create an array and add elements to it, we will now see how to delete items from an array.

Let's start by creating an array. In Ruby, an array can contain elements of different data types, so let's build an array that contains strings, integers, and Booleans:

x = ["asdf", 3, 4, 12, "asdf", "b", true, 34, 2, 4, 4, 4] 

If we want to delete all the 4 elements from the array, we can run the following code:

x.delete(4) 

If we print x, we can see all elements except the 4 elements.

You can check the length of the array before and after deleting all the 4 elements. When you place x.length before the delete method, your array will return a value of 12. Also, if you run the length method after deleting the values of 4, your array's length will only be 8.

Now if I want to remove the element 12...
