React Developer Tools give a lot of power to inspect the React component tree, and look at props, event handlers, etc. However, what I'd really like to do is to be able to inspect those data structures in the browser console.
You can check the reason for a component's (re)render with the React Devtools profiler tool. No changing of code necessary. See the react team's blog post Introducing the React Profiler. First, go to settings cog > profiler, and select "Record why each component rendered".
I am learning react-hooks, I created a series of state variables using useState, when trying to debug and see its value I find that React Developer Tool does not show the name assigned to the state variable but the text State, this is inconvenient as it is not possible to identify from the beginning which variable is the one that is tried to debug

What worked for me was unintalling react-devtools: npm uninstall -g react-devtools, which I had installed globally; and then re-installing it back as a dev-dependency: npm install react-devtools --save-dev. and also don't forget to reload your app through the React native debugger after launching the react-devtools i.e npx react-devtools
This will mean that I cannot use this old trick, which means that I cannot use react developer tools to debug anymore which will make debugging the frontent much harder. Is there any way that I can use react developer tools on the desktop app, or can I somehow setup the localhost server so that I can just run it in a webbrowser with react dev ...
Also, locally you could just comment that part of code. Search all file in "node_modules" for "React DevTools", you will get 2 results, react-dom.js and ReactDOM.js: react-dom.js, navigate to line 5430, make line 5430 - 5437 to a comment, save. ReactDOM.js, navigate to line 68, make line 68 - 75 to a comment, save.
