I'm curious about how various frontend frameworks handle bindings between the DOM and JavaScript. I know that JavaScript offers tools like MutationObserver for watching properties, which makes it easier to set up bindings. However, I'm not sure if using attribute bindings is the best approach since not all changes are managed through attributes—especially with things like form input values and properties like clientWidth or clientHeight that require different methods like ResizeObserver. How do popular frameworks deal with two-way bindings and ensure that changes in the DOM reflect in their internal states?

In React, there's no built-in concept for two-way binding. Instead, you manually attach event listeners, and those listeners update the state, which triggers a re-render. It's more of a controlled approach where you explicitly handle how state reflects input changes.
