Traditionally, React class components were used for state management, but with the introduction of React Hooks, the process has become simpler and more intuitive. In this blog, we will dive deep into the fundamentals of React.js, understanding the significance of components and the need for state...
React is a powerful JavaScript library for building user interfaces, and one of its most powerful features is the Context API. The Context API allows developers to manage the state of their application without the need for cumbersome prop drilling. Th
which is useful for cases where the next state does not depend on the first state, such as setting data from an API that overrides old values. Then it will run through how to set a state as the current state, which is useful when the next state depends on the current state, such as...
In this article, I will introduce the React Context API for state management and create a similar solution as Redux without using a third-party library. React Context API It’s actually not a new idea. Context API has been a part of React for a long time, but only in an experimental ...
Redux:Redux is a powerful state management library commonly used with React. It provides a predictable state container and helps you manage complex application states effectively. Redux can be particularly useful when your React application grows in size and requires centralized state management. It ...
With an error boundary, you isolate parts of the app and handle errors locally.An error boundary is a React component that implements the componentDidCatch() lifecycle event, and wraps other components:class ErrorHandler extends React.Component { constructor(props) { super(props) this.state = {...

Redux is an application state management library for JavaScript. It can be used with UI frameworks or layers in JavaScript, including React. React Redux is a Redux UI binding library for React, which binds the two libraries together and helps optimize performance between them. Hooks are functions...
Lack of Built-in Immutability: React strongly encourages immutability to facilitate efficient rendering and state management. The “for” loop does not inherently provide immutability guarantees, and modifying objects or arrays within a loop can lead to unintended side effects and make it difficult to...
You have a React.js application that includes components, state management, and API interactions. You need to write unit tests for individual components, integration tests for API interactions, and end-to-end tests for critical user flows. ...
