Sometimes we want to perform operations outside the scope of this data flow process, like interacting with an API. These operations are called side effects. In this article, we will explore how to handle side effects in React using a hook called useLayoutEffect.

React ref provides a means of accessing DOM elements in this article you will learn how and when to use refs, and how refs can be useful outside the DOM.

This post explores the new react context API. We will explore why we need react context, how it works high-level with example use cases and at what point should React developers reach out to context API to solve their problems. Our sample use case will then show you how to use React context with som

Suspense refers to React's new ability to “suspend” rendering while components are waiting for something and display a loading indicator. React suspense allows you to write cleaner React components that are performant and are easy to maintain. This article explains what React Suspense is and How it

The useMemo hook is used for memoizing values in React Applications. useMemo memoizes computed values in a React component so that in cases of a component re-render, those values will not be recomputed. This article will teach you what a useMemo hook is and how to use it.

State management means keeping track of how our data changes over time. In React, we can manage state with hooks or using an external state management library like Redux. In this article, we will explore a hook called useReducer and learn about its capabilities for state management.

Redux is a state management library for JavaScript apps. In this article, we will walk over React-Redux and how to use it. We will use it to simplify the complex state management of membership and authentication flows.

In this article, we’ll understand what React Custom Hooks are, the benefits of using them and when to use them. We’ll also learn how to build two custom hooks and show them in use.
