 React is declarative: you tell React _what_ to render, and React will figure out _how_ best to display it to your user. To do this, React has a few phases where it runs your code.

-_Rendering_ refers to calculating what the next version of your UI should look like. After rendering, [Effects](/reference/react/useEffect) are _flushed_ (meaning they are run until there are no more left) and may update the calculation if the Effects have impacts on layout. React takes this new calculation and compares it to the calculation used to create the previous version of your UI, then _commits_ just the minimum changes needed to the [DOM](https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model) (what your user actually sees) to catch it up to the latest version.
