Svelte vs React

Whenever people think about building a quality app with the help of the JavaScript framework – React is sure to tick their minds. Although there are a number of other frameworks available at their disposal, the newest yet one of the most promising JavaScript frameworks arrived is the Svelte. While decision making Svelte vs React, about whether to choose good old React or newbie Svelte for app building, many of us remain perplexed. As features offered by Svelte are much similar to the former one but Svelte is still undergoing development.

So, here we will have a look over their features and have a smart Svelte vs React comparison to get an overview of both the frameworks in a quick manner.

What is Svelte?  

Svelte is a JavaScript-based framework used for making interactive pages in web development.

For web development, Svelte offers a galore of features like any other existing web frameworks like React and Vue but the main feature is the unique ability to compile and convert UI components within the code that can be updated to the DOM.

Svelte since its launch in 2016 has undergone a lot of changes and right from its earliest version to the current version it has received a significant reaction.

Currently, the number of sites using Svelte is continuously swelling and is preferred by many top companies due to its high-performance output and rich user interface.

Advantages of Svelte

  • Svelte through declared variables offers automatic updates of data to interface to ensure a smooth user experience
  • Svelte with the absence of a Virtual DOM feature helps to boost the speed, smooth user interface, and effortless interactions, thereby boosting user engagement
  • Svelte allows the usage of actual business logic without getting mired in coding complexities, which makes it work over much fewer codes
  • Svelte being a light-weight framework ensures that the website built is clean and highly user-focused interface
  • Svelte being much cleaner and having simpler codes has a much lower learning curve, as anyone with a background in JavaScript can being with a project

Drawbacks of Svelte

  • Svelte being newer than others as a framework is not mature as compared to others, as best practices are still taking place and has a very smaller user base for community support
  • Svelte at present does not have many tools for app debugging and testing, therefore it is not suitable for all projects
  • Svelte does not have any protocol when it comes to accommodating concurrent requests on displaying certain content on the basis of priority or loading sequences, so while working with content-rich websites it can undermine the user experience

What is React?

React JS is an open-source mobile application framework developed by Facebook for developing apps and websites.

React Native allows a developer to build real and exciting mobile applications that can run on different platforms such as Windows, Android, iOS in JavaScript by compiling to native app components.

React Native comes with large community support as it has great popularity due to its features it gave huge competition to the long-time favorite Angular JS.

Advantages of React 

  • React refreshes the user interface for updating data, which in turn increases the efficiency and loading speed of web pages
  • React by optimizing the codes and enhancing the code readability gives a better user experience and speed 
  • React by updating data in the virtual DOM, ensures optimal performance which in turn helps in faster loading of web-pages
  • React by separating logic and controls allows maximum reusability of components, which thereby speeds the development process
  • React being much older in comparison to Svelte, has a much larger community of developers for continuous support for projects

Drawbacks of React 

  • React incorporates developer contributions from worldwide and is updated frequently, so staying in tune with the latest versions of React or keeping a tab over it is much harder
  • React uses JSX, which combines both JavaScript and HTML. Therefore, compared to simple JavaScript coding it is a barrier for new beginners to learn 
  • React focuses only on the UI Layers of the app, but not the Model and controller in the app architecture. So, you need to choose some other technologies to get done integrating additional routing or API tools in the project

The race between Virtual DOM and Real DOM

One of the most glaring differences between them is that Svelte is a compiler that converts application into ideal JavaScript during building. Whereas React uses Virtual DOM to interpret the application code during the runtime.

React Virtual DOM (Document Object Module)

Virtual DOM React is a representation of the DOM (Document Object Module), which is otherwise is a programming interface used to represent the page so that programs can change the document structure, style, and content.

Using DOM usually results in performance bottle-neck and can even result in an annoying user experience, so here React comes with the solution of virtual DOM.

Here in virtual DOM, any change first performed on the virtual DOM, which lives in memory, but not over the screen and this leads to providing higher performance along with a pleasant user experience.

So which framework Svelte vs React you must choose?

Well, as per scenario and requirement choices can differ, so here’s a quick take –

A small start-up would certainly require a simple structure application, so here in this case Svelte would be highly preferable. A developer well-versed in common web languages can easily handle Svelte, so delivering app results can be easy.

Here in the second scenario take a large enterprise needing multiple integrations and wanting many plugins to functions, so here React would be an ideal choice to opt for.

React has already its proven user experience and performance specific attributes, which are time tested. Again, in the case of a developer who needs any assistance regarding any issue in the development of a web project, you always have a large global community at your disposal to seek or discuss.

Conclusion

As we see from the above discussion that both React and Svelte have various pros and cons as well-equipped frameworks.

React in the current time have everything as a framework and conveniently is in a commanding position compared to Svelte which is still in a nascent stage.

As of now both React and Svelte are efficient tools to build great user interfaces, and choosing any one of them must be purely on basis of your requirement and scenarios, as both Svelte vs React offer some of the other features to woo the users.
