-### Deprecation warnings for JavaScript files
-
-As a general rule we can't enable the `deprecation/deprecation` rule for JavaScript files because this rule requires TypeScript type information to work. If you have a mixed TypeScript/JavaScript project then you can enable it for the JavaScript files inside your TypeScript project using the following override:
-
-```js
-// .eslintrc.js
-module.exports = {
-  overrides: [
-    {
-      // This must be a valid path inside your TypeScript source folders.
-      files: ["src/**/*.{js,jsx}"],
-      rules: { "deprecation/deprecation": "warn" },
-    },
-  ],
-};
