* and ** in ruby methods and more.

In the ruby you can use ** or hash in the methods. Here is the some examples plz follow this with me.

[37] pry(main)> def test2(data={})
[37] pry(main)*   ap data
[37] pry(main)* end  

Here you can put any number of data using symbol key and values like we used for creating hash and this will be captured by element.

[40] pry(main)> test2(hello:'data',say:'data')
{
    :hello => "data",
      :say => "data"
}
=> nil

Note: Here we have used gem 'awesome_print' for the beautiful print.

There is another way of writing the same function.

[28] pry(main)> def test(**data)
[28] pry(main)*   print data
[28] pry(main)* end
