Describe 'Custom Renderers' in Vue 3.

Vue 3 allows you to create a custom runtime by providing your own DOM-like API to the createRenderer function.

Vue's core reactivity and component logic are separated from the DOM. You can create a renderer that targets Canvas, WebGL, iOS/Android native views, or even terminal output. You just need to implement a set of functions for creating elements, inserting them, and updating attributes.
