Interactive rating component solution -- Radio Buttons with Plain JS

Any feedback will be much appreciated :)

How I did it:

• I loop through all the radio button and pass the iterative object to query selector to dynamically get the option that user select.
• Get user's input value when the submit button have been click on then show it in DOM.

Question: I would like to try to go with object oriented way such as event target to select an element in the group so that I don't have to write loops all the time. If anyone know please tell me I'll be super thankful.
