Introduction State management is a crucial aspect of every application, especially in React. While hooks like useState() and prop passing can take us quite far, complex scenarios often call for a dedicated state management library. One such library I’ve come to appreciate is the easy-peasy library, built on top of Redux. With its simplified approach to handling state, it allows for cleaner and more manageable code. Installation To start using easy-peasy, simply install it using the following npm command:...

Looking back at the last decade of JavaScript and the evolution of the web, it has been a truly remarkable journey. In 2010, JavaScript wasn’t as widely used as it is today. While I had JavaScript books from as early as 1998 in my library, I mainly used it in the form of Mootools and jQuery plugins. Although I wrote some glue code in JavaScript, it wasn’t anything groundbreaking. Back then, JavaScript was not considered a hot language, except for projects like GMail and Google Maps that required advanced work and large budgets....

In the world of React, immutability is a significant concept that plays a crucial role in the development process. Whether you agree with it or not, React and its ecosystem strongly encourage the use of immutability. It is essential to understand why immutability is so important and the implications it has. In programming, immutability refers to a variable whose value cannot be changed once it is created. You might not realize it, but you are already using immutable variables when working with strings....

Learning React may seem like a daunting task, but with the right resources and a consistent approach, you can become a React master. In this blog post, we will guide you through the optimal path to go from zero to proficient in React. Before diving into React, it’s essential to have a solid understanding of JavaScript. If you are just starting out, take the time to explore the fundamentals of JavaScript....

The React Context API is a powerful tool for managing state in your React applications. It allows you to pass state across different components without the need for manual prop drilling. This API simplifies the process of state management and can be used as an alternative to libraries like Redux. To understand how the Context API works, you first need to create a context using the React.createContext() function: const { Provider, Consumer } = React....

In React, when you want to return more than one element from a component, you usually wrap them in a div to satisfy the requirement of returning a single element. However, this approach adds an unnecessary div to the output. To avoid this, you can use React.Fragment. Here’s an example of how to use React.Fragment: import React, { Component, Fragment } from 'react'; class BlogPostExcerpt extends Component { render() { return ( <React....

In this blog post, we will discuss how to interact with the state of your React components. The state is a crucial part of managing component data and handling user interactions. Setting the Default State To set the default state of a component, you need to initialize this.state in the constructor. For example, let’s consider a BlogPostExcerpt component with a clicked state: class BlogPostExcerpt extends Component { constructor(props) { super(props); this....

React, the popular JavaScript library, has revolutionized the world of visual interface development. Whether you’re a beginner or an experienced developer, learning React can take your skills to the next level. In this blog, we will explore why React is so widely used and how it can solve common development problems. Developed by Facebook and released in 2013, React has become the backbone of numerous applications, including Facebook and Instagram. Its success lies in its ability to simplify user interface development by breaking it down into manageable components....

React StrictMode is a powerful tool that allows you to enable a range of checks performed by React, providing valuable warnings and insights. By utilizing the built-in component React.StrictMode, you can easily enable these checks within your React application. To implement React StrictMode, one straightforward approach is to wrap your entire App component with <React.StrictMode></React.StrictMode> in the index.js file. Here’s an example: import React from 'react'; import ReactDOM from 'react-dom'; ReactDOM....

Discover how React Portals can improve your component rendering process. React 16 introduced a powerful feature called Portals. With Portals, you can render an element outside of its component hierarchy, in a separate component. This means that even though the element is rendered elsewhere in the DOM tree, it is still managed by the React component hierarchy. To use React Portals, you can make use of the ReactDOM.createPortal() API, which takes two arguments: the element to render and the DOM element where it should be rendered....
