红宝石 |数组 any?() 操作

any?()是一个 Array 类方法，它检查是否存在模式并将集合的每个元素传递给给定的块。

Syntax: Array.any?()

Parameter: array for testing

Return: true if the block ever returns a value other than false or nil otherwise return false.

示例 #1：

# Ruby code for any?() method
  
# checking pattern
puts "pattern : #{%w[geeks or geeks].any? { |word| word.length <= 3 }}\n\n"
  
puts "pattern : #{%w[dot grow cat].any? { |word| word.length >= 4 }}\n\n"

输出 ：

pattern : true

pattern : true

解释 ：

In above code two conditions are giving i.e.
– word_length should be equal or less than 3 and
– word_length should be equal or greater than 4
If the pattern follows it (as in the code), it results yes otherwise false

示例 #2：

# Ruby code for any?() method
  
# checking pattern
puts "pattern : #{%w[geeks or geeks].any?()}\n\n"
  
puts "pattern : #{[].any?}\n\n"

输出 ：

pattern : true

pattern : false

解释 ：

In this code
part a) – true as it returns a pattern
part b) – false as it returns nil pattern
