HighlightsLanguage-aware rulesESLint v10.2.0 adds support for language-aware rules through the new meta.languages property. Rule authors can now explicitly declare which languages a rule supports, and ESLint will throw a runtime error if that rule is enabled for an unsupported language, as specified by the language configuration option.Here is an example of a rule that only supports the JavaScript language:const rule = { meta: { type: "problem", docs: { description: "Example JavaScript rule", }, languages: ["js/js"], }, create(context) { return {}; },};123456789101112Copy code to clipboard Currently, none of the ESLint built-in rules restrict the languages they are designed to work with, but this may change in the future.More information about the meta.languages property can be found in the custom rules documentation.Temporal supportWith the Temporal proposal now at TC39 stage 4, ESLint v10.2.0 recognizes Temporal as a built-in global. As a result, the no-undef rule no longer flags Tem

HighlightsAPI Support for Bulk SuppressionsESLint v10.1.0 introduces API support for the bulk suppressions feature that was previously only available in the CLI.ESLint API consumers, such as IDEs, can now pass the applySuppressions: true option to the ESLint constructor. With this option, suppressions from the suppressions file are automatically applied to results from ESLint#lintFiles() and ESLint#lintText() methods.const eslint = new ESLint({ applySuppressions: true, // optional, defaults to `eslint-suppressions.json` suppressionsLocation: "./config/my-suppressions.json",});123456Copy code to clipboard Please see the Bulk Suppressions - Usage with the Node.js API section for more details.Featuresff4382b feat: apply fix for no-var in TSModuleBlock (#20638) (Tanuj Kanti)0916995 feat: Implement api support for bulk-suppressions (#20565) (Blake Sager)Bug Fixes2b8824e fix: Prevent no-var autofix when a variable is used before declaration (#20464) (Amaresh S M)e58b4bf fix: update eslint (#
