Template file for each page in this case?

I do a lot of snippets of code to test html and code small projects.
Usually I create an empy folder with a blank HTML document and an assets folder to hold all the supporting scripts/images.

Could someone here more familiar with WordPress than myself tell me how I could go about doing so on my WordPress site?

Do I need to create a new template file for each snippet then go into the panel and add a new page each time?

Hope this question is clear?
