One common performance concern when using the Context API for global state is the lack of ________, which can lead to unnecessary re-renders.

  • shouldComponentUpdate
  • PureComponent
  • memoization
  • reactivity
The missing feature in the Context API that can lead to unnecessary re-renders is memoization. Memoization helps prevent re-renders when the data hasn't changed, which is essential for optimizing performance. The other options, such as shouldComponentUpdate and PureComponent, are related to class components in React, and reactivity is a broader concept not specifically related to the Context API.
