Why should load functions be free of side effects?

// +page.js
import { user } from "./state.svelte.js";
export async function load({ fetch }) {
  user.current = await (await fetch("/api/user")).json();
}

• ✓Correct answer: Writing to shared state from load leaks data between users on the server and makes data flow unpredictable; return data instead
• 2Load functions can't assign variables
• 3It slows down the build
