A hook that checks if the code is running on the browser or the server.

  • Create a custom hook that returns an appropriate object.
  • Use typeof window, window.document and window.document.createElement to check if the code is running on the browser.
  • Use the React.useState() hook to define the inBrowser state variable.
  • Use the React.useEffect() hook to update the inBrowser state variable and clean up at the end.
  • Use the React.useMemo() to memoize the return values of the custom hook.
