In React we'll often be manipulating arrays through state management. There are many ways to achieve full CRUD but we need to remember one golden rule:

NEVER MUTATE STATE DIRECTLY

This is to say, never directly change an array, always create a copy and manipulate the copy!

We use two methods and the spread operator to create our array copies that will replace state.

• The spread operator allows us to easily add a new item to a copy
• The .map method allows us to create a new array and change one item (or items)
• The .filter method allows us to create a new array and remove an item (or items)
