["Hip", "hip", "array!"] We have learned about how to store groups of data into arrays in Swift. 🙌

Here are some of the things that we covered:

• An array is a list of ordered items.

  var evenNumbers = [2, 4, 6, 8, 10]

• The first index in an array is 0.
• The .count property that returns the size of an array.
• Some of the methods that come with arrays:
  • .append(): adding an item to the end
  • .insert(): adding an item to an index
  • .remove(): removing an item from an index
• The for-in loop can be used to iterate through an array.
