Hash#<=() is a Hash class method which compares two Hash values.

Syntax: Hash.<=()

Parameter: Hash values

Return: true – if a <= b otherwise return false

Example #1 :






# Ruby code for Hash.<=() 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}
  
  
# COMPARING TWO Hash VALUES
puts "Hash a <= b : #{a<=b}\n\n"
  
# b
puts "Hash b <= c : #{b<=c}\n\n"
  
# c
puts "Hash a <= c : #{c<=a}\n\n"

Output :

Hash a <= b : true

Hash b <= c : false

Hash a <= c : true

Example #2 :




# Ruby code for Hash.<=() 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}
  
  
# COMPARING TWO Hash VALUES
puts "Hash a <= b : #{a<=b}\n\n"
  
# b
puts "Hash b <= c : #{b<=c}\n\n"
  
# c
puts "Hash a <= c : #{c<=a}\n\n"

Output :

Hash a <= b : false

Hash b <= c : true

Hash a <= c : false
