However, HTML doesn't let you create reusable templates. If you wanted to create a new page, you would need to copy and paste the above snippet and edit the header and content yourself. This isn't great if we have a lot of content on our site that shares a lot of similar layout. The smart people who created React also had similar thoughts, inventing the concept of JSX Components to solve the code duplication problem. However, HTML doesn't let you create reusable templates.

In effect, components allow you to write a JavaScript function that takes some data and produces HTML as an output. **While Quartz doesn't use React, it uses the same component concept to allow you to easily express layout templates in your Quartz site.** In effect, components allow you to write a JavaScript function that takes some data and produces HTML as an output. **While Quartz doesn't use React, it uses the same component concept to allow you to easily express layout templates in your Quartz site.**

Component files are written in `.tsx` files that live in the `quartz/components` folder. These are re-exported in `quartz/components/index.ts` so you can use them in layouts and other components more easily.

Each component file should have a default export that satisfies the `QuartzComponentConstructor` function signature. It is a function that takes in a single optional parameter `opts` and returns a Quartz Component. The type of the parameters `ops` is defined by the interface `Options` which you as the component creator also decide.

While this prevents most typing mistakes *within* our nominal typing system (e.g. mistaking a server slug for a client slug), it doesn't prevent us from *accidentally* mistaking a string for a client slug when we forcibly cast it.

Thus, we still need to be careful when casting from a string to one of these nominal types in the 'entrypoints', illustrated with hexagon shapes in the diagram below.
