To use dispatch with useContext, you need to make sure that you have created a context using createContext() and that you have wrapped your component with the context provider. Here are the steps you can follow to avoid the Uncaught TypeError error:

  1. Create a context using createContext():
import { createContext } from 'react';

const MyContext = createContext();
  1. Wrap your component with the context provider:
<MyContext.Provider value={{ dispatch }}>
  <MyComponent />
</MyContext.Provider>

In this example, we are passing an object with a dispatch function as the value prop to the provider.

  1. In the component that needs access to the dispatch function, use useContext to retrieve the context and access the dispatch function:
import { useContext } from 'react';
import MyContext from './MyContext';

function MyComponent() {
  const { dispatch } = useContext(MyContext);

  // Use the dispatch function here
}

By using useContext, we can retrieve the dispatch function from the context without having to pass it down the component tree through props.
