Access elements of nested hashes using dig method
The dig method in Ruby’s Hash class allows us to access nested hash elements using a sequence of keys as arguments
Syntax:
nested_hash.dig(key1, key2, …)
Example: In this example, we use dig method to access the value by passing the keys as arguments
# Example nested hash
nested_hash = {
key1: {
key2: {
key3: "geekforgeeks"
}
}
}
# Access elements of nested hashes using dig method
value2 = nested_hash.dig(:key1, :key2, :key3)
puts "Value: #{value2}"
Output
Value: geekforgeeks
