A tool to help developers know if a browser specific feature is available in all chosen browsers or not

So, imagine you create a browserslist config and have a CLI tool or something similar that you can prompt whether a CSS/JS feature or API is supported in every single browser your config includes or not. Wouldn't that be awesome? Is there a tool like that?

You can use https://github.com/amilajack/eslint-plugin-compat along with ESLint for JS. For CSS you could use https://github.com/anandthakker/doiuse (though the project hasn't been updated in a while) or https://github.com/ismay/stylelint-no-unsupported-browser-features with Stylelint (also based on doiuse). All tools use your browserslist data (e.g. in .browserslistrc) to detect which browsers you support.

That's awesome! Thank you for these tools, I've been searching for them for a long time
