I put the starting score to 0 further down in my code

All the examples seem to put the starting "score" variable set to 0 at the beginning of the script. I put mine after all the question prompts. Does it matter? Why might putting it at the top be considered cleaner code?

Hey Gregory,

As you alluded to in the end of your question, it is a best practice to declare your var/let/const variables in the beginning of your code. Although the practice may have little to no effect on personal or small projects, it can be a nightmare for someone to assist with debugging / collaboration as code bases grow larger. I personally couldn't put it any better than w3schools best practices ( https://www.w3schools.com/js/js_best_practices.asp )which states that putting declarations on top will: Give cleaner code Provide a single place to look for local variables Make it easier to avoid unwanted (implied) global variables Reduce the possibility of unwanted re-declarations

Hope this helps
