> [!hint]
> For those coming from React, Quartz components are different from React components in that it only uses JSX for templating and layout. Hooks like `useEffect`, `useState`, etc. are not rendered and other properties that accept functions like `onClick` handlers will not work. Instead, do it using a regular JS script that modifies the DOM element directly.
As the names suggest, the `.beforeDOMLoaded` scripts are executed *before* the page is done loading so it doesn't have access to any elements on the page. This is mostly used to prefetch any critical data.

The `.afterDOMLoaded` script executes once the page has been completely loaded. This is a good place to setup anything that should last for the duration of a site visit (e.g. getting something saved from local storage).
If you need to create an `afterDOMLoaded` script that depends on *page specific* elements that may change when navigating to a new page, you can listen for the `"nav"` event that gets fired whenever a page loads (which may happen on navigation if [[SPA Routing]] is enabled).

It is best practice to also unmount any existing event handlers to prevent memory leaks.
#### Importing Code
Of course, it isn't always practical (nor desired!) to write your code as a string literal in the component.
Quartz supports importing component code through `.inline.ts` files.

import * as d3 from "d3"
document.getElementById('btn').onclick = () => {
alert('button clicked!')
document.getElementById("btn").onclick = () => {

```
Additionally, like what is shown in the example above, you can import packages in `.inline.ts` files. This will be bundled by Quartz and included in the actual script.
### Using a Component
After creating your custom component, re-export it in `quartz/components/index.ts`:

Then, you can use it like any other component in `quartz.layout.ts` via `Component.YourComponent()`. See the [[configuration#Layout|layout]] section for more details.
