MERN stack application development is mostly centered around ReactJs, NodeJs & MongoDB at the core. React has 154.4K GitHub stars & 30.3K GitHub forks. Node too boasts 72K GitHub stars. Companies like Uber, Slack, Coursera & Netflix use these technologies for building their customer-focused products. Of-course this could not justify choosing mern stack for your application but such humongous love & support does instills one’s trust in these technologies.
