Hash#dig() is a Hash class method which finds the nested value which is specified by the sequence of the key object by calling dig at each step.
Syntax: Hash.dig()
Parameter: Hash values
Return: nested value which is specified by the sequence of the key object by calling dig at each step. otherwise nil
Example #1 :
# Ruby code for Hash.dig() method # declaring Hash value a = {a: 100 , b: 200 }
# declaring Hash value b = {a: 100 , c: 300 , b: 200 }
# declaring Hash value c = {a: 100 }
# Dig Value puts "Hash a dig form : #{a.dig(:a)}\n\n"
puts "Hash b dig form : #{b.dig(:c)}\n\n"
puts "Hash c dig form : #{c.dig(:a)}\n\n"
|
Output :
Hash a dig form : 100 Hash b dig form : 300 Hash c dig form : 100
Example #2 :
# Ruby code for Hash.dig() method # declaring Hash value a = { "a" => 100 , "b" => 200 }
# declaring Hash value b = { "a" => 100 }
# declaring Hash value c = { "a" => 100 , "c" => 300 , "b" => 200 }
# Dig Value puts "Hash a dig form : #{a.dig(" a ")}\n\n"
puts "Hash b dig form : #{b.dig(" a ")}\n\n"
puts "Hash c dig form : #{c.dig(" b ")}\n\n"

Output :
Hash a dig form : 100 Hash b dig form : 100 Hash c dig form : 200
