JSCS v2.1.0 Release Notes

  • Overview

    🚀 In this release, we added three more rules: two of them are ES6-only, they "protect" you 👀 from the downside of arrow functions (see 1 and 2 for an explanation of why you might want to enable them) and another universal one if you like to keep your object neat and tidy.

    🚀 Airbnb, jQuery, and Wordpress presets are now using some of the new rules we added in the previous release. Whereas, the wikimedia preset is now less strict for JSDoc comments.

    🚀 This release also includes a JSON reporter, lots of bug fixes and enhancements, plus couple new rule values for your linting pleasure.
