+#### Migrating to `defineConfig(...)`
+
+The core `defineConfig(...)` helper is a nearly exact clone of `tseslint.config(...)` that was [first released in ESLint v9.22.0](https://eslint.org/blog/2025/03/eslint-v9.22.0-released/).
+See [the ESLint blog post](https://eslint.org/blog/2025/03/flat-config-extends-define-config-global-ignores/#support-for-older-eslint-versions) for info on how to use `defineConfig(...)` with older versions of ESLint.

+
+{/* prettier-ignore */}
+1. Overriding `files` in `extends`.
+   When `files` is provided in both a base object and an extension, `tseslint.config(...)` _overrides_ the `files` property in the extension, whereas `defineConfig(...)` semantically intersects the two provided `files` specifiers.

+   There are slight differences in the way types are declared between the two functions, which may cause typechecking errors when you switch from `tseslint.config(...)` to `defineConfig(...)` in some cases (see [#10899](https://github.com/typescript-eslint/typescript-eslint/issues/10899) for an example that used to impact typescript-eslint's own configs).
+   Type errors such as these do not indicate a runtime problem and can safely be ignored.
