add key and value to hash ruby
To add a key and value to a hash in Ruby, you can use the following code:
hash = {}
hash[:key] = "value"
Explanation:
1. Create an empty hash using the curly braces {}
.
2. Use the square brackets []
to specify the key and assign a value to it using the assignment operator =
.
That's it! The key-value pair has been added to the hash.
