After running the command below, it appears that jsxhint is analyzing the compiled files by webpack:
webpack-dev-server --devtool eval --colors --progress --content-base ./build
The warnings I receive are as follows:
const '$__0' has already been declared. @ line <n> char <m>
This warning is generated for approximately 30% of the files in my application.
The warnings mention specific line and character numbers which correspond to the processed files accessible in Chrome DevTools under the
Sources Tab > webpack:// > . > relative-path-to-fileI even went as far as deleting the entire application along with all node modules and cloning it again from the repository, but the issue persists.
The problem started after updating the node modules in the package.json file post-deletion of the node_modules folder. Reverting back to previous versions of all dependencies did not resolve the issue.
