+title: useComponentDidMount
+tags: hooks,effect,beginner
+---
+
+A hook that executes a callback immediately after a component is mounted.
+
+- Use `React.useEffect()` with an empty array as the second argument to execute the provided callback only once when the component is mounted.
+
+```jsx
+const useComponentDidMount = onMountHandler => {
+  React.useEffect(() => {
+    onMountHandler()
+  }, []);
+}
+```
+
+```jsx
+const Mounter = () => {
+  useComponentDidMount(() => console.log('Component did mount'));
+
+  return <div>Check the console!</div>;
+}
+
+ReactDOM.render(<Mounter />, document.getElementById('root'));
+```
