Javascript Programming Tutorials, Guides & Best Practices

• Reducers: Define actions to manipulate the state (addUser, updateUser, deleteUser).
• Async Actions: Handle API calls with createAsyncThunk.
• Extra Reducers: Manage different states (loading, succeeded, failed) based on async actions.

In src/app/store.js, configure the Redux store:

  const person = { name: 'Alice', age: 25 };
  const name = Reflect.get(person, 'name');
  console.log(name); // Output: Alice

• Reflect.set: Sets the value of a property on an object.

import React, { Suspense } from 'react';

const LazyComponent = React.lazy(() => import('./LazyComponent'));

function App() {
  return (
    <div>
      <Suspense fallback={<div>Loading...</div>}>
        <LazyComponent />
      </Suspense>
    </div>
  );
}

export default App;

In this example, LazyComponent is only loaded when it’s needed, and a loading message is displayed while it’s being fetched.
