How Do I Efficiently Update Nested State Properties in React?

Updating Nested State Properties in React

When trying to organize React state using nested properties, it may be noticed that simply setting the nested property directly does not work. Instead, a slightly different approach is required.

To update nested state properties, create a copy of the nested object, make the desired changes to the copy, and then use setState to replace the original state object with the updated copy. Here's an example:

var someProperty = {...this.state.someProperty}
someProperty.flag = true;
this.setState({someProperty})

In highly nested states, this approach becomes cumbersome. To simplify, consider using the immutability-helper package, which provides helper functions for deeply updating nested objects in a concise manner.
