Description

Sect. “State Updates May Be Asynchronous” may profit from more information:

  • The example is very helpful, as is the sentence “React may batch multiple setState() calls into a single update for performance”.

  • However, “asynchronous update” confused me (“delayed” may have been a better word). Only the following tweet made it completely clear: https://twitter.com/dan_abramov/status/824309659775467527

  • Thus: maybe explain a little more and/or use example and explanation from the tweet.

Research direction

Start with the linked “State Updates May Be Asynchronous” section in the React documentation and review the referenced tweet for the intended explanation. Clarify what “asynchronous update” means and how batching affects setState(), while preserving the helpful example; the section should be understandable without relying on the tweet.
