One of the quickest web development frameworks available is React.js. It is the best option for interactive design due to its widely used single-page application development. However, React is not alone in this; other JS frameworks also offer a significant increase in performance speed compared to conventional JS architecture.

But what makes React better than others?

There are several reasons for that. Let us look at 3 main reasons that give React the upper hand over other frameworks.

Virtual DOM

The virtual DOM is a virtual representation of the Document Object Model in which the user interface is stored independently from the actual DOM in local memory. React uses reconciliation to synchronize it with the actual DOM. It is a process of linking several DOM classes and matching virtual representation to virtual operations.

The primary goal of the virtual DOM is to speed up the update process. As SPAs and web apps got more popular, smaller interactions began to occur on the page. Because the page does not reload in SPAs, developers must update a single element – the one with which users interact – but this is not what a DOM does.

Faster Libraries

Businesses opt for React to create a simple and interactive user experience. React.js components are relatively straightforward; you don’t have to deal with gigabytes of data. The application’s web interface is simple to create and update; it loads rapidly and responds to user actions.

Google is an example of how simple interfaces and React-based libraries contribute to an interactive and speedy interface. A simple UI boosts the speed of React-based sites, which is yet another argument to assert that React is faster.

Boosted by Redux

Redux is a JavaScript application state management tool. The core concept of Redux is that the entire state of the app is held in a single area. Every application element can directly access the application state without passing props to child components or calling back data to parents.

Although Redux is compatible with many different frameworks, including Angular, Vue, Preact, and vanilla JavaScript. But, React is generally augmented by Redux and is used to provide unidirectional data flow and operate with immutable data.

This centralizes all data and makes it very simple for a component to obtain the required state. As a result, when designing large, complex apps with many components, the Redux store is what you should go for.

React in comparison with other Frameworks

React vs Angular.js

According to Google Trends, React and Angular was quite popular in development in prior years. Furthermore, analysts predict they will be a huge success in the upcoming years. However, as you can see, React is more popular among developers than Angular.

Each framework has its size and syntax restrictions to which it must adhere. It adds to the size of the codebase and influences its overall performance. When developing a tiny application, the difference is barely discernible. However, for large projects, these nuances tend to collect.

In comparison to Angular, React is a small library. You have a lot more leeway and fewer “necessary” components. In contrast, Angular is a full-fledged framework that connects numerous components.

If you know how to organize the application efficiently, React will most likely be the fastest alternative. Angular may save more time in the long term for less experienced developers.

The pace of basic activities, such as creating and editing rows, is similar in Angular and React. The outcome is determined by the version & codebase. However, the average values show nearly similar performance.

In terms of memory allocation, Angular is marginally faster. However, this distinction will be obvious in large projects. Angular may be too large for little things.

React.js vs Vue.js

Vue.js, like React, favors minimalism and reusability. When compared to React, it is more general. Vue defines the application structure more strictly than React – after all, it’s a framework, not a library. Nonetheless, its features are simple, which contributes to its quickness.

React js & Vue js comparison

Vue.js, like React, enables the creation of interfaces using reusable components. You write cleaner code and have fewer dependencies, which helps with performance.

The separation of JavaScript and HTML code is one of the key differences between Vue and React. Vue, like React, separates JS and HTML into templates. The structure of the page on the HTML template and its interaction logic in JS can be described. When you change one template, the system changes another. React, on the other hand, employs JSX files, a hybrid of JS and HTML.

As a result, React’s code is smaller and thus lighter. However, there is a disadvantage: Vue.js may be easier to navigate and change. Codebase quality will determine the final speed. The team must select which interface will function best.


The bottom line is that Vue and Angular are both fast frameworks. Despite being larger than React, this greater functionality has advantages such as more possibilities and a much clearer organization. When choosing between these three frameworks, speed and performance should not be your primary considerations. Compare philosophy, key concepts, functionality, and ecosystem instead.

The key to sustaining high performance and speed is; regularly monitor component performance, discover problems, and test speed in various circumstances. Remember dynamic elements such as the amount of data entered, the number of rendering requests, pagination, and so on are responsible for the speed. As a result, teams must keep optimization at the top of their priority list at all times; otherwise, problems will pile up.
