Learn advanced topics of React for building dynamic user interfaces with reusable components, allowing for efficient updates and rendering.

Zero to Hero in Front-end Development with React

React is one of the front-end frameworks of JavaScript. This module starts with the Context API, refs, error boundaries, portals, and code splitting. Next, we will learn about hooks, Redux and routing, and internationalization. After completing this module, we will be able to use React professionally.

React Deep Dive: Advanced Approaches

## The `options` parameter

If you actually want to use the fourth (`options`) parameter of the `connect()` method, you should really know what you're doing. Redux is optimized to only ever really need these options in very rare edge cases. For example, you can define your own context for Redux to use or define functions that compare whether a component needs to be  re-rendered or not. This list is a complete summary of the options available:

```js
{
  context: Object,
  pure: boolean,
  areStatesEqual: Function,
  areOwnPropsEqual: Function,
  areStatePropsEqual: Function,
  areMergedPropsEqual: Function,
  forwardRef: boolean,
}
```

If you feel like you might need these options (Spoiler alert: in most cases, the answer is "No, you don't need these"), you should check out the [official documentation](https://react-redux.js.org/api/connect#options-object).
