Svelte vs React: What is Svelte?
When should you use Svelte?
Programs written in Svelte are useful for application in low-capacity or low-power devices. Svelte tools and frameworks provide enhanced control over state management, routing, and building customized infrastructure. Svelte is useful for DOM manipulation, reactive frameworks, and emerging markets.
Which companies use Svelte?
Svelte vs React: What is React?
React is useful for state management and for rendering that state onto the DOM. The development of React applications requires the usage of additional libraries. The knowledge of routing, client-side coding, and design patterns is a prerequisite for developing React components.

When should you use React?
React is a flexible component library that is perfect for state management. Thus, websites and apps that use React components can exchange data without reloading the page. React should be used for user interfaces that require a lot of user interaction.
React corresponds to ‘view’ in the model-view-controller. Thus, managing lower-level algorithms with React is easy, and coding is required only for the interface’s view model. React’s Virtual DOM improves website performance and reduces lags to enhance loading times.
Which companies use React?
Highly successful organizations like Meta, Instagram, Salesforce, Shopify, Discord, Skype, and Pinterest use React to develop user interfaces. Due to the availability of a large number of developers globally, companies prefer React to create the front-end part of their websites.
React is fast, easy to implement, and scalable, making it a popular choice among developers and organizations.

Svelte vs. React: Which is better?
React and Svelte are both popular choices for building modern web applications. While they have similarities, they differ in key areas such as learning curve, performance, bundle size, state management, tooling and ecosystem, developer experience, and debugging
Svelte, on the other hand, has a relatively low learning curve. Its template language is easy to learn, and developers can quickly get up to speed with the framework. Svelte also has a small API surface, which means that there are fewer concepts to learn.
Traditional Document Object Model (DOM) triggers an update with each code change, which slows down the app’s performance. Virtual DOM speeds up the process by acting as temporary memory storage for changes made to the user interface. A process known as diffusion or reconciliation delays updates until updating and rendering can be carried out effectively.
Svelte acts as a compiler that carries out DOM rendering through reactive programming. Whenever an assignment triggers a change in the component stage, the DOM is updated. Thus, as a serverless-first framework, Svelte is considered more reactive than React.
Svelte’s .gzip version has a size of 1.6 kilobytes. On the other hand, React.gzip, when combined with ReactDOM, comes to a total size of 42.2 kilobytes. Svelte’s smaller bundle size ensures better loading speeds, better responsiveness, and reduced bandwidth costs.
The next point of comparison in the React vs Svelte battle is state management. React’s state management is based on a unidirectional data flow, where the state is passed down from parent components to child components. Now this approach can lead to complex code, especially when dealing with large and complex applications.
Svelte, on the other hand, uses a reactive approach to state management. This approach means that the UI automatically updates when the data changes, which makes it easier to manage the state of the application.
Code written in React can be tested with ‘end-to-end’ tests. React code of an application is tested in a realistic browser environment. This reduces your app’s time to market (TTM) and boosts its value.
Svelte offers its testing library for unit testing. The Svelte testing library is smaller in size than React and offers simple computations. Thus, Svelte can help developers maintain clean, functional, and compressed code.

Tooling and ecosystem
Tooling and ecosystem are important factors to consider in the Svelte vs React battle. React has a large ecosystem of third-party tools and libraries, while Svelte’s ecosystem is still growing. However, Svelte’s small API surface and efficient compiler make it easier to use without the need for additional tools and libraries.
As you know, developer experience is important for productivity and maintaining code quality. React’s component-based architecture makes it easy to reuse code and build complex UIs quickly. Svelte’s template language and reactive programming approach make it easy to build UIs quickly and efficiently.
The fact that a large-scale organization like Meta (Facebook) maintains React keeps React developers in high demand.

Svelte is rather uncommon, but developers report high levels of satisfaction while using Svelte. The enterprise-level support for Svelte is fairly new, as Sveltekit 1.0 is yet to be released. The Svelte community is small, with only 11k developers, compared to more than 287k active React developers.
Another important point when looking at the Svelte vs React battle is debugging. React’s debugging tools are well-developed and widely used by the community.
Svelte’s debugging tools are less developed than React’s. However, this doesn’t mean that they are any less effective. Svelte’s compiler generates highly optimized code, which can make debugging more challenging. However, Svelte’s small API surface makes it easier to debug applications.
When it comes to maintenance, React wins over Svelte because it is maintained by Meta and a team of individual developers and companies. As a result, React has a dedicated team that works on the framework 24/7. But that’s not it! In the past few years, React saw quite a few big releases like functional components React Context, Hooks, etc., making it a favorite among many developers.
But Svelte is no less. Svelte has an amazing maintenance team that works to keep the framework at the top of its game and in contention with React.
To conclude: when should you use Svelte and when should you use React?
Svelte and React have their own advantages and disadvantages. React is backed by Meta and hence quite reliable. Also, it’s a good choice for big projects that demand several features. React is also suitable for making complex user interfaces as it’s easy to create reusable components with the framework. Last but not least, React has a range of built-in features and tools. So if you need to develop large applications quickly, choose React.
React vs Svelte: Who wins?
Consider your project requirements and the time you have first. The Svelte vs. React argument is straightforward when these two aspects are clearly defined. Use Svelte if performance and optimized code are your priorities. You can also go for Svelte for your projects to achieve a smaller bundle size, maintainable code, and exceptional performance without the VDOM. Due to the simplicity of the framework, Svelte enables developers to prepare a website faster.
But if you need to build heavy, complex applications quickly, go for React. React makes it easy to maintain the stability of your application. An active community of React developers helps resolve doubts and bugs observed during development.
If you’re an employer, using React for your projects will make it easier to hire software developers.

Is Svelte better than React?
What is better Svelte or React in 2023?
React and Svelte are excellent choices if you’re looking to build user interfaces. While React is great for building larger applications efficiently, Svelte is better suited for smaller applications demanding high performance.
Should I switch from React to Svelte?
If your priority is performance and optimized code, then go for Svelte. But if you’re looking to build large and complex applications quickly, then React may be the better option. In addition, if you want to build dynamic user interfaces, then Svelte is the better choice.
Is Svelte smaller than React?
Yes, Svelte is smaller than React in terms of bundle size because Svelte compiles your code at build time, resulting in smaller and more efficient code. On the other hand, React uses a larger runtime library to manage the component state and update the DOM. However, the actual size difference will depend on the specific project and its dependencies.
Is Svelte worth learning?
Svelte is a better choice for small to medium-sized projects with simpler components, where fast performance and a small codebase are essential.
React is more suitable for large-scale projects with complex components and state management requirements, where a larger ecosystem of tools and libraries is needed.
