+- **Type:** `Function`
+
+- **Arguments:**
+  - `{Function} done`
+
+- **Details:**
+
+  Called after compilation is finished, right before the `ready` hook - but **only** during dynamic component swapping or in the initial render for static components. Unlike other lifecycle hooks, it accepts a `done` callback, which must be called for the rest of the lifecycle to complete. It's most useful for performing some asynchronous operation before a component is swapped in, like fetching data from an API.
