Calling Ruby methods various ways.

Calling methods for a object other than `dot operator`.

Sample class:

class User

  def awesome_method1
    puts "##############"
    puts "Inside method 1"
    puts "##############"
  end

end

Using dot operator(Normally used).

_user = User.new
_user.awesome_method1

=====Output====
###############
Inside method 1
###############

Using send method.

_user = User.new
_user.send :awesome_method1

=====Output====
###############
Inside method 1
###############

Using method(:method_name).call.

_user = User.new
_used.method(:awesome_method1).call

=====Output====
###############
Inside method 1
###############

The major difference between dot, send and method(:name).call is last two will call the private, protected methods as well.

Happy Coding :)
