This project will require you to use inverse dataflow and declarative state updates.

• Open the terminal
• Run npm install
• Run npm start

• As a user, I should be able to:
  • Read a list of poems
  • Create a new poem
  • Delete an existing poem
  • Update the content of an existing poem

• Remember that inverse dataflow is the process of "creating your own events"
• Simply pass a function as a prop to another component, and invoke the function there

• Make your input visible: Log state, and any variables you're using when updating state, before you call setState
• Make your output visible: Log state at the beginning of your render method
• Think of declarative state updates like puzzles. You can see your input, you can see your output, how is the output different from the desired output and what can you change to get you closer?

The spread operator can be used to copy the contents of an Array or Object into a new Array or Object.

The .filter iterator takes in a callback, and returns a new array containing every element for which the callback returned true Example:

[1, 2, 3, 4, 5].filter( num => num > 3) // => [ 4, 5 ]

The .slice method takes in two numbers, a starting index an ending index, and returns an array with the elements between the two indexes
