The ESLint configuration currently in use was last updated four years ago. A lot has changed in the JavaScript since then. Let's update the configuration to match today's standards.

Manual testing scenarios

This is a coding standards change and does not make any changes to any functionality within the platform. Therefore no testing of Magento itself is required.

Questions or comments

I expect this pull request to spark some conversation. Many of the settings here have come from the JavaScript Standard Style, although some adaptations have been made to better fit with Magento's existing style guide (eg, four spaces for indentation). I have intentionally kept all existing settings unchanged.

I'm happy to receive feedback here, but may need to get someone from Magento to give a deciding vote / official stance if consensus cannot be amicably achieved.
