First thing we're going to do is erase all this so we can get some space to work here, so if you want to take a look at these later on, you can take a look at the exercise files. So, the first thing we're going to do is aTuple, so I'm going to first put the syntax and then explain what it is. So, let's go and do a let aTuple and then we'll declare it with an array and then initialize it with some values. So, basically aTuple is a type of array that you can insert multiple types and let me just add some stuff here to make a little bit more sense. So, in this type of array, you can actually have more than one type.
