+Disallows CommonJS export assignments through `exports` and `module.exports`.
+
+Use ECMAScript module exports instead. For a named export, declare or export the
+binding with `export`; for a default export, use `export default`.
+
+**Invalid:**
+
+```typescript
+exports.answer = 42;
+module.exports = function answer() {
+  return 42;
+};
+module.exports.answer = 42;
+```
+
+**Valid:**
+
+```typescript
+export const answer = 42;
+
+export default function answer() {
+  return 42;
+}
+```
