            Answered 2022-Mar-15 at 16:08

            I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.

            So, do this:

            • In package.json, update the line "babel-eslint": "^10.0.2", to "@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3.
            • Run npm i from a terminal/command prompt in the folder
            • In .eslintrc, update the parser line "parser": "babel-eslint", to "parser": "@babel/eslint-parser",
            • In .eslintrc, add "requireConfigFile": false, to the parserOptions section (underneath "ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have)
            • Run the command to lint a file

            Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.

            b. If number is -0𝔽 and lowest is +0𝔽, set lowest to -0𝔽.

            c. If number < lowest, set lowest to number.

            1. Return lowest.

            Note that in most cases, +0 and -0 are treated equally, also in the ToString conversion, thus (-0).toString() evaluates to "0". That you can observe the difference in the browser console is an implementation detail of the browser.

            Answered 2021-Oct-15 at 00:55

            ESLint 8.0.0 comes with a breaking change for rules that provide suggestions. There is nothing you can put into your .eslintrc.js to make it work if you use rules that haven't been updated to work after this change.

            What you can do:

            • Use ESLint 7 until the plugin is updated to work with ESLint 8.
            • In case of eslint-plugin-react-hooks, the offending rule has already been updated (check this line on GitHub), it's just that there hasn't been a stable release of the package since. However there have been daily alpha releases, at the time of writing the latest version is 4.2.1-alpha-c3a19e5af-20211014. If you really need both ESLint 8 and this plugin, you can use an alpha version until the next stable version comes out.
