Can you interrupt an arbitrary user-written function that's called inside the rendering stack?
- philipp-spiess 8y agoNo, that's not possible in JavaScript. The important part is that React components are lazily evaluated[1] and are not rendered as a stack. So React can render a few components and then pause for higher priority work. As a user of the framework, you don't need to care about this though. So your mental model can be that of an interruptable function. [1]: https://overreacted.io/react-as-a-ui-runtime/#lazy-evaluation https://overreacted.io/react-as-a-ui-runtime/#lazy-evaluatio...
- ivanwonder 8y agoI think to interrupt a render means interrupt the process of reconciliation. you don't have to response the user input until the difference of whole React element has been found. https://overreacted.io/react-as-a-ui-runtime/#consistency https://overreacted.io/react-as-a-ui-runtime/#consistency
