In turn, annotating the `load` function with `PageLoad`, `PageServerLoad`, `LayoutLoad` or `LayoutServerLoad` (for `+page.js`, `+page.server.js`, `+layout.js` and `+layout.server.js` respectively) ensures that `params` and the return value are correctly typed.

If you're using VS Code or any IDE that supports the language server protocol and TypeScript plugins then you can omit these types _entirely_! Svelte's IDE tooling will insert the correct types for you, so you'll get type checking without writing them yourself. It also works with our command line tool `svelte-check`.
