Hashes (Part 1)
Hashes are simply arrays that link one object to another object (think of it as an association of sorts), say like Spagthetti_sauce which is part of the complete menu, referring to the hash Spaghetti_sauce gives you the ingredients. Same as with arrays, they are created with the “.new” method resulting in an empty hash.
salad = Hash.new
Using curly braces, you get to assign the hash its elements like the example shown below:
salad = {
green salad => ‘lettuce and sweet basil’
coleslaw => ’shredded lettuce, garlic and onions, carrots’
garden fresh => ‘cherry tomatoes, lettuce, iceberg, iceberg lettuce, mayonnaise, olive oil, lemons
}
