Why Is It Good For Your App To Use React JS?

If you prefer a resource-light approach and want a development project that is accessible and quick to deploy - both now and in the future - React JS has a lot to offer.

It’s well supported, regularly updated and highly adaptable. Whether you’re building an entire web application, a new mobile component or even a standalone SPA, React JS development has much to offer.

For more advanced challenges, React JS also pairs nicely with React Native. Not only do both use JavaScript, but React Native also uses React JS for base abstraction - leading to two very coherent solutions. This is best for more mobile-specific solutions, where native support is a larger requirement.

Our employees love React JS development.

We wanted to move away from implementing each new feature multiple times on different code bases. We wanted to minimize duplication of effort. We ultimately decided to build our new client on top of React JS and React Native.

Eric Traut from Microsoft is satisfied with using React Native.
