Refactor 2

[michaeltintiuc]

This is the second step of refactoring:

• Standardize our components
• Simplify rendering
• Remove some of the direct DOM access
• Added cleanup code

All of our components share the same basic properties of left and top meaning that we've just laid the foundation for one of the next steps, leveraging HOC and utlity functions, it is much easier to work with those if we standardize our code.

We've also removed a good chunk of conditionals by using basic arithmetic for rendering animation frames

We've replaced fetching canvases by ID with useRef

We've also added cleanup code to our useEffect where we clear our timeouts and intervals.
