Update state-and-lifecycle.md #9562
Conversation
While reading the documentation it seemed to me that the documentation could be improved for beginners by a short example on how to update child properties of state and a link to further reading.

Thanks for taking the time to do this @steadycoding.
I don't think we should introduce immutability-helper here, it will likely only serve to confuse beginners who aren't familiar with its syntax.
Though I agree that it's useful to briefly mention how to updated nested properties. It might be better to mention this in the section on not mutating state. We could even link to this section on not mutating data.
The only place where you can assign this.state is the constructor. If you need to update nested properties make sure you do so without mutating
this.state. See The Power Of Not Mutating Data for more on that.

Thank you for submitting this PR! 😄 Unfortunately the documentation and source code for reactjs.org has been moved to a different repository: https://github.com/reactjs/reactjs.org If you are willing, please open a new PR there. Sorry for the inconvenience! (For more backstory on why we moved to a new repo, see issue #11075) |
