interactive rating component main using DOM

Hey, great job with your solution!

My only suggestion is regarding accessibility. Since you used span elements as the rating options, it's impossible to navigate between them using the keyboard (Tab to focus, arrow keys to choose an option, and Enter key to select/submit). So, instead, you could use radio buttons, which have these functionalities native implemented, and get the selected value from the submitted form. You can check this Star Rating example from the Web Accessibility Initiative to get an idea.
