Here are a few factors making React leading technology: Code reusability. The codebase made with React is easily-reusing. It significantly reduces the development and modification costs and also saves funds for project support. Cross-platform development. With this advantage, you build applications for several platforms, paying only one development team and creating one product. Affordable UI cost. This factor is due to the previous one. When you develop an application for multiple platforms at once, you do the same with design. A unified, optimized design is not only financially beneficial but also serves for a better user experience. Community support. Since React is one of the most world popular stacks, it's easy to find lots of ready-made solutions and libraries in the public domain. Moreover, you'll have no problem with a shortage of expert coders.
