Hash#to_proc() : to_proc() is a Hash class method which returns a Proc which maps ‘keys’ value to ‘value’ value.
Syntax: Hash.to_proc()
Parameter: Hash values
Return: Proc which maps ‘keys’ value to ‘value’ value.
Example #1 :
# Ruby code for Hash.to_proc() 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}
# to_proc Value puts "Hash a to_proc form : #{a.to_proc()}\n\n"
puts "Hash b to_proc form : #{b.to_proc()}\n\n"
puts "Hash c to_proc form : #{c.to_proc()}\n\n"
|
Output :
Hash a to_proc form : # Hash b to_proc form : # Hash c to_proc form : #
Example #2 :
# Ruby code for Hash.to_proc() 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}
# to_proc Value puts "Hash a to_proc form : #{a.to_proc()}\n\n"
puts "Hash b to_proc form : #{b.to_proc()}\n\n"
puts "Hash c to_proc form : #{c.to_proc()}\n\n"

Output :
Hash a to_proc form : # Hash b to_proc form : # Hash c to_proc form : #
