Why is it best to use React.js For Web app Development?

Whether you are a rookie in development or a well-experienced coding expert, chances are you have heard about React.js. Being one of the most up-and-coming languages in web development, the popular front-end development framework took the world by storm back when introduced in 2011.

Since then, React.js has been used to develop more than 200,000 websites, according to a report by BuiltWith , and the number is on a constant rise. So, it is pretty implied that React.js has a lot to offer and possesses many abilities that make it a shining star among other front-end development technologies.

Today, we will unravel the secret behind the incredible success of React.js and why you should choose React.js for your web application development needs.

Benefits of react.js in web app development


First and foremost comes the performance. React ensures its optimal performance by minimizing DOM changes. Before React, most frameworks and libraries would update the DOM unknowingly to reflect a new state. This resulted in changes to a significant part of the page

React detects the values of each component's State via virtual DOM. And, when a component's state changes, React compares the existing DOM state with what the new DOM should seem like. Later, it finds the least expensive way to update the DOM. Developers can rapidly build an interactive web application using react.

Virtual DOM

The virtual representation of a UI is stored in memory and synced with the real DOM by a library such as ReactDOM. This process is known as reconciliation. This method enables the declarative API of React: Tells React what State you want the UI to be in, and it makes sure the DOM matches that State. This abstracts out the manipulation, event handling, and manual DOM updating that you would otherwise have to use to build your app.

Easy Testing

React's design is very user-friendly for testing.

  • Modern UI browser testing is difficult. On the other hand, require very little or no configuration for testing in React.
  • Other UI browsers require browsers for testing but can test React components fastly and easily using the node command line.
  • Command-line testing is fast and can run a reasonable amount of test suites at a time. On the other hand, UI browser testing is slow.
  • Modern UI browser testing is often time-consuming and complex to maintain. React tests can be written quickly using tools like Jest.

Easy Data Flow

The flow of data in react-redux starts at the component level when the user communicates with the application UI. This linking leads to action creators dispatching an action. When an action is sent, it is accepted by the root reducer of the application and sent to all the reducers.

Why is ReactJS so popular?

  • Reactjs enables developers to code their apps within JavaScript. JSX is one of the most significant features that make ReactJS easy. Coders can create a new UI feature and see it appear in actual time easily. It brings HTML directly into your JS.
  • Components of Reactjs allow developers to break down complex UI. The concept of components is what makes ReactJS special.
  • Props in ReactJS make allow custom data or properties to a specific UI component to pass. Through props, developers can out components using custom data.
  • The State makes it achievable to store all the changes in one section. With State, a single web application becomes very simple because all the details are sourced from one section.

How to develop web apps using React.js?
