NOTE:

There are 2 rules to remember about reference:
1. The value of the reference is persisted (remains unchanged) between component re-renderings;
2. Updating a reference doesn't trigger a component re-rendering.

2 main differences between reference and state:
1. Updating a reference doesn't trigger re-rendering, while updating the state makes the component re-render;
2. The reference update is synchronous while the state update is asynchronous.
