What we just showed you was hash literal notation. We call it that because you literally describe what you want in the hash: you give it a name and you set it equal to one or more key => value
pairs inside curly braces.
You can also create a hash using Hash.new
, like so:
my_hash = Hash.new
Setting a variable equal to Hash.new
creates a new, empty hash; it’s the same as setting the variable equal to empty curly braces ({}
).
Instructions
1.
Use Hash.new
to create a new hash called pets
. Hash
must be capitalized, or Ruby won’t know what you’re talking about!
