First things first: let’s create a hash to hold our movies and their ratings. Next, let’s prompt the user for input so we can eventually store movie/ratings pairs in our hash.

favorite_foods = {
  vegetable: 'broccoli'
}
puts "Do you like coding in Ruby?"
answer = gets.chomp

1. A hash is a way of storing data with a specifiable key, as opposed to an array where the data is only accessible using numbers (or indices). It is created using a pair of curly braces { }.
2. puts displays a message in the console. In this example, we ask if you like coding in Ruby.
3. In order to get the user input, we have to call .chomp on gets.
