Access elements of nested hashes using square brackets

In this method, square brackets are used with keys to access nested hash elements.

Syntax:

nested_hash[key1][key2]…

Example: In this example, we use square brackets with keys to access nested hash elements

Ruby
# Example nested hash
nested_hash = {
  key1: {
    key2: {
      key3: "w3wiki "
    }
  }
}

# Access elements of nested hashes using square brackets
 
value1 = nested_hash[:key1][:key2][:key3]
puts "Value: #{value1}"

Output
Value: w3wiki
