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:
import { createContext } from 'react';
const MyContext = createContext();
<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.
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.
