Additional Important Points to Remember
- Since the StrictMode is a developer tool, it runs only in development mode. It does not affect the production build in any way whatsoever.
- In order to identify and detect any problems within the application and show warning messages, StrictMode renders every component inside the application twice.
What is StrictMode in React ?
The React StrictMode can be viewed as a helper component that allows developers to code efficiently and brings to their attention any suspicious code that might have been accidentally added to the application. The StrictMode can be applied to any section of the application, not necessarily to the entire application. It is especially helpful to use while developing new codes or debugging the application.
