How does ReactJS render faster than Vue.js?

With the ever-increasing demand for faster rendering of web pages, what sets ReactJS and Vue.js apart in terms of performance? It’s an interesting question that has been studied by experts in the coding field. Generally speaking, the key difference rests upon the different ways that each technology has been designed as well as the level of support that is available.

One of the major differences between ReactJS and Vue.js is the manner in which the libraries have been developed and tested. According to reports from Gartner Research and Mediamarkt, ReactJS’ library has seen significantly more development and testing as compared to Vue.js. This has resulted in improved reliability, and therefore, more consistent rendering speeds for the ReactJS framework. Additionally, ReactJS has a higher level of user and developer community support than Vue.js, which can help ensure better performance.

In addition, the author will explain why ReactJS tends to offer faster render speeds that Vue.js. With this information, web developers will have a better understanding of which of these technologies works best for different types of projects.

Definitions and Explanations of ReactJS and Vue.js

ReactJS is a JavaScript library created by Facebook which is designed to make it easier to build user interfaces. It makes use of a virtual DOM, which is essentially a copy of the web page stored in memory, allowing for a faster rendering of the web page than if all the underlying HTML code had to be processed. Vue.js is an open-source JavaScript framework designed for creating user interfaces. Its design is geared towards the creation of innovative web applications with high performance and flexibility.

ReactJS is often seen as the faster of the two when it comes to rendering because it can quickly update the virtual DOM (an abstracted copy of the web page) in memory. When any part of the page changes, only the incremental differences need to be rendered, leading to faster loading times than if the entire page had to be re-rendered. Vue.js does not use a virtual DOM, which means it has to process all the HTML code in order to render a page. This is a more time-consuming process, leading to faster rendering times with ReactJS.

1. Exploring How ReactJS Renders the UI

ReactJS is a JavaScript library that is rapidly becoming an industry standard in front end development due to its flexible, efficient, and component-oriented design. It is the choice of many developers for building user interfaces and single page applications. React is well known for its fast rendering capabilities, and this article will explore in detail how React renders the UI for faster performance.

Virtual DOM Rendering

One of React’s main advantages is its virtual DOM rendering. This is a system whereby React updates the DOM with the minimum amount of steps possible, so that the user is presented with a fast and efficient user experience. Without this virtual DOM system, React would have to update the entire DOM every time there was a change in the data or state of the application.

The virtual DOM works by comparing the current state of the DOM with the updated version of the DOM, and then changes only the necessary elements that actually need to be changed. By doing this, React renders the UI much faster.

React Compiler

Another reason that React renders the UI faster is its compiler. This compiler takes the React code and converts it into vanilla JavaScript code. This means that the code runs faster because it is not being interpreted into a different language, rather it is already in the language that the browser understands. This means faster rendering times because the browser only needs to read the code and execute it, rather than translating the code each time into an executable form.

React Natively Code

React’s coding language is also designed to render faster than Vue. The language is designed to be intuitive, meaning that writing React code is faster than other frameworks. As a result, developers can spend more time writing complex logic and integrating their components with other frameworks, rather than spending time writing code that is more time consuming and inefficient.

Lastly, React is easier to use than other frameworks, which makes it faster to develop with, and thus render faster. It allows for developers to easily build reusable components, meaning that they can quickly build applications with no code reorganisation or testing needed. This provides greater flexibility and scalability than other frameworks, reducing time spent developing the UI.

ReactJS and Speed

ReactJS is renowned for its focus on increasing speed and efficiency. By utilising memory-efficient coding techniques and optimised components, ReactJS helps developers create high-performance applications and user interfaces. ReactJS offers virtual DOM, the fastest way to sync UI and data, which helps to rapidly render user interfaces without reloading the page. Furthermore, ReactJS allows developers to build components once, and reuse them as many times as needed which saves time.

Vue.js and Speed

Vue.js is another popular JavaScript library, which was created as an attempt to combine the best aspects of the most popular frameworks. Like ReactJS, Vue.js also uses virtual DOM, but its execution of virtual DOM is less efficient then ReactJS, which results in a slower rendering of user interfaces. Although Vue.js can work with the same setup as ReactJS, Vue.js requires multiple lines of code, which decreases performance.

Additionally, Vue.js hot module replacement affects the speed of rendering; first, the real DOM is updated and then the server-side rendering. It is natural that high update frequency decreases the speed of rendering. Although, both frameworks have many other advantages, ReactJS renders UI faster than Vue.js. It is not to say that Vue.js is without value, but ReactJS may be the more appropriate solution for those looking to create faster applications and user interfaces.

3. Analyzing How Vue.js Differs from ReactJS

“So much complexity in software comes from trying to make one thing do two things.” — Ryan Singer

ReactJS and Vue.js are two popular JavaScript libraries that enable developers to build user interfaces of single page web applications (SPAs). Both ReactJS and Vue.js help to facilitate a more organized codebase, with ReactJS using the JSX syntax while Vue.js uses templates. Both libraries are useful when it comes to making interactive user interfaces, but ReactJS and Vue.js do differ.

Components and DOM

ReactJS and Vue.js both have the ability to create reusable components, but ReactJS does so with a virtual DOM. This virtual DOM allows for a much faster response from ReactJS, as only the changed parts of a webpage need to be re-rendered with each update. This makes ReactJS particularly useful when making complex web pages and applications.

Syntax and Design

When it comes to creating the structure of a webpage, ReactJS again has a slight advantage. Vue.js uses HTML-based templates which provides more flexibility in terms of which ways the HTML code can be written. ReactJS on the other hand uses the JSX syntax which is a JavaScript extension.

Ultimately, both ReactJS and Vue.js are great libraries which can both be used to great ends. ReactJS is suitable when creating large, intricate web applications, while Vue.js is better when creating smaller, less complex applications. Either way, ReactJS can still render faster than Vue.js with its virtual DOM.


Have you found yourself wondering which JavaScript framework is the best for peak performance? When it comes to speed, ReactJS and Vue.js stand at the forefront of the pack – but which is the faster of the two?

To answer this question, we must look to the very foundations of the two frameworks. While ReactJS makes use of a Virtual DOM – a ‘memory-less virtual representation of a DOM’ – Vue.js employs a Virtual DOM that strives to increase performance. As a result, both ReactJS and Vue.js accelerate the rendering process, allowing developers to create amazing user interfaces with increased efficiency.

Despite the similarities in approach, ReactJS appears to outpace Vue.js when it comes to rendering. This is due to the fact that ReactJS’s methods for implementing and updating the Virtual DOM are more sophisticated and complex than those used in Vue.js. While the difference might be small, this can have a huge impact on the performance of the framework.
