- `todoApp.todo.delete(...)` and `todoApp.todo.create(...)` functions are dynamically created by the ABP Framework, thanks to the [Dynamic JavaScript Client Proxy](../../UI/AspNetCore/Dynamic-JavaScript-Proxies.md) system. These functions perform HTTP API calls to the server and return a promise, so you can register a callback to the `then` function as we've done above.
