“We’ve heard you: One of the biggest reasons ESLint users haven’t upgraded to ESLint v9.x is migrating a configuration file seems difficult and complicated. Some plugins support flat config and the ESLint v9.x rule APIs and some don’t. Sometimes you need to use FlatCompat and sometimes you need to use the compatibility utilities. While we cover as much as we can in the migration guide, it can take time to walk through your configuration and make the necessary changes.”

“That’s why we’re excited to announce the release of the ESLint Configuration Migrator. This utility is designed to translate .eslintrc.* files into eslint.config.js files [...]”

“Presenting a date in a specific format often brings to mind some JavaScript libraries right away, such as moment.js and, more recently, date-fns. Although these libraries still satisfy very peculiar use cases, they are no longer essential for simple date formatting.”

“Widely supported by browsers since 2016, and currently with approximately 96% global coverage, the native Intl API can present dates in highly elaborate formats. And most importantly, all this without adding even 1Kb to your application.”
