Why do we recommend React.js


React has the most optimized way to update virtual dom, which provides high speed.Excellent community support. The React repository is in the top 5 most sought-after ones on GitHub; The Reactiflux community of over 100,000 members has been created specifically for React developers. More than 200,000 questions on StackOverflow - the most well-known resource for developers - are dedicated to the topic of React and related libraries. Great performance and dev experience - a small number of concepts required for training, humble library size, a small API, simple programming model - all this makes React a favorite technology of a huge number of engineers. Reusable code - which saves time, makes the product more flexible and scalable. JSX syntax keeping the code as simple and elegant as possible makes React a perfect solution for enterprise-scale projects. Testing-friendly. The use of Jest & Enzyme tools, and the command line, significantly simplifies and speeds up QAs' work.

React vs Angular

Both React and Angular have robust ecosystems, and they are both suitable for building large projects. However, sometimes React is still a better solution. For example:Using React you’ll get a lighter debugging process compared to Angular; It’s impossible to use JSX working with Angular; Angular uses a real document object model, so you’ll have a lower implementation speed using it compared to virtual DOM. React software development services are the best for creating SPA. Dynamic pages made using Angular work are stodgy because of their heavy size.

React vs Vue

React community is much larger than Vue has. It means that using Vue you’ll face a lack of skilled engineers; A limited set of plugins and components compared to React; Vue has a language barrier - almost all documentation is written in Chinese, which is a substantial challenge.
