Real-World Example

In the case of a login process, you might want to update the login hook when the logic changes:

import { createBefter, hook, callHook } from "@farming-labs/befter";
const hooks = createBefter();

// Add initial login hook
let { currHook } = hook(hooks, "login", () => console.log("Logging in..."));

// Call the initial hook
await callHook(hooks, "login");

// Update the login hook with new functionality
await updateHook(hooks, "login", currHook["login"][0], () =>
  console.log("Logging in with new logic..."),
);

// Call the updated hook
await callHook(hooks, "login");
