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
