Different ways to call a method in Ruby

less than 1 minute read

Ruby has many ways of doing the same thing, for instance when you have an array to get its size you could either use one of the following methods: Array.size, Array.length, Array.size or Array.count. When it comes to calling methods on objects in Ruby one has a number of alternatives to choose from, some are just fancy ways to use in the commdand line and should not be used in actual code.

  1. Method One.
 str = "Calling Methods"
 str.upcase # CALLING METHODS

  1. Method Two.
 str = "Calling Methods"
 str.send(:upcase) # CALLING METHODS

  1. Method Three.
 str = "Calling Methods"
 m = str.method(:upcase)
 m.call # CALLING METHODS

And that is it for today.
