Ruby | Hash to_a method

Hash#to_a() is a Hash class method which gives a nested array of the key-value pair.

Syntax: Hash.to_a()

Parameter: Hash values

Return: array representation of the hash

Example #1 :




# Ruby code for Hash.to_a() 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_a Value
puts "Hash a to_a form : #{a.to_a()}\n\n"
  
puts "Hash b to_a form : #{b.to_a()}\n\n"
  
puts "Hash c to_a form : #{c.to_a()}\n\n"

Output :

Hash a to_a form : [[:a, 100], [:b, 200]]

Hash b to_a form : [[:a, 100], [:c, 300], [:b, 200]]

Hash c to_a form : [[:a, 100]]

Example #2 :




# Ruby code for Hash.to_a() 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_a Value
puts "Hash a to_a form : #{a.to_a()}\n\n"
  
puts "Hash b to_a form : #{b.to_a()}\n\n"
  
puts "Hash c to_a form : #{c.to_a()}\n\n"

Output :

Hash a to_a form : [["a", 100], ["b", 200]]

Hash b to_a form : [["a", 100]]

Hash c to_a form : [["a", 100], ["c", 300], ["b", 200]]
