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
