ESLint v8.52.0 released

Highlights

Unused eslint-enable directives

The CLI option --report-unused-disable-directives and the config option reportUnusedDisableDirectives:true now also report and autofix unused eslint-enable directives. An eslint-enable directive is considered unused if it doesn’t match with any eslint-disable directives, meaning that it doesn’t re-enable any rules.

/* eslint-disable no-console */

console.log("hello");

/* eslint-enable no-continue -- this directive is unused */
