How to create an Empty Map in Ruby

How to create an Empty Map in Ruby ?

To create an empty map in Ruby, you can use the Hash.new constructor. This creates a new, empty Hash object.

We can create an empty map in Ruby using the Hash.new constructor, which initializes a map with no key-value pairs.

For example,

We start by declaring a variable named empty_map. This variable will hold our empty map.
We then use the Hash.new constructor to create a new, empty Hash object. In Ruby, the Hash.new method initializes the map with no key-value pairs.
The newly created map is now assigned to the empty_map variable. In this example, the map is empty and ready to store key-value pairs.
We can now perform various operations on this empty map, such as adding key-value pairs, checking for the presence of keys, and retrieving values.

empty_map = Hash.new

# Operations on the empty map
# ...

puts empty_map

{}

In this tutorial, we learned How to create an Empty Map in Ruby language with well detailed examples.
