Summary

Follow this link to debug the react source code yet failed: https://legacy.reactjs.org/docs/how-to-contribute.html

Steps: 1). Make no changes to main branch and just run the yarn build command 2). Open the fixtures/packaging/babel-standalone/dev.html file which includes your changes, but meet the errors from browser console as below:

GET file:///Users/quinvon/Documents/GitHub/react/build/oss-experimental/react/umd/react.development.js net::ERR_FILE_NOT_FOUND
dev.html:4 
        
        
       GET file:///Users/quinvon/Documents/GitHub/react/build/oss-experimental/react-dom/umd/react-dom.development.js net::ERR_FILE_NOT_FOUND
babel.js:61666 You are using the in-browser Babel transformer. Be sure to precompile your scripts for production - https://babeljs.io/docs/setup/
runScripts @ babel.js:61666
transformScriptTags @ babel.js:336
(anonymous) @ babel.js:327
Inline Babel script:2 Uncaught ReferenceError: ReactDOM is not defined

I think your debug way of source code is out of date!

@Rekl0w, I saw it, and where's the new guidance about how to debug the source code?
