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

True or False: Error boundaries can catch errors in their child components, but not in the error boundary component itself.

True or False: Error boundaries can catch errors in their child components, but not in the error boundary component itself.

Catching rendering errors in child components.

Catching errors in asynchronous code like `setTimeout` or `fetch`.

What are error boundaries mainly used for in React?

What are error boundaries mainly used for in React?

Only Class components can be turned into an error boundary.

The class using it has to either implement the `static getDerivedStateFromError()` method or the class method `componentDidCatch()` or both.

The class using it does not have to implement the `static getDerivedStateFromError()` method and the class method `componentDidCatch()`.

Only Function components can be turned into an error boundary.

What are the rules of an error boundary?

They should be children of their child components that they want to protect.

They should be parents of their child components that they want to protect.

Where should error boundaries be placed?

True or False: Error boundaries are used to counteract empty screens when exceptions might be thrown by React.

True or False: Error boundaries are used to counteract empty screens when exceptions might be thrown by React.
