WORK O' THE DAY: 

═══════════════════════════

At this point you should be very comfortable iterating through your arrays.

Today we're going to work on manipulating the elements (items) inside the array. Two of those commands (insert & append) seem to be much the same.

They are NOT. Please have a conversation to COMPARE and then CONTRAST those two terms in how they effect your array.

Let's try-- load this code into a new app and compare it to THIS

 

 

Now remix your code and make a version that allows your user to

• insert an item to your array after they have added the initial 20 characters

• Remix your code again and create a version that allows your user to append an item to your array after they have added the initial 20 characters

• Remix your code again and create a version that allows your user to remove an item to your array after they have added the initial 20 characters
