Ruby | Hash any?() function

any?() is a Hash class method which checks for the presence of a pattern and passes each element of the collection to the given block.

Syntax: Hash.any?() Parameter: Hash for testing Return: true - if the block ever returns a value other than false or nil otherwise return false

Example #1: Ruby

# Ruby code for any?() 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}

# checking pattern
puts "pattern : #{a.any?()}\n\n"

puts "pattern : #{b.any?()}\n\n"

Output :

pattern : true

pattern : true

Example #2: Ruby

# Ruby code for any?() method

# declaring Hash value
c = {}

puts "pattern : #{c.any?}\n\n"

Output :

pattern : false
