The main purpose of using MERN stack is to develop apps using JavaScript only. This is because the four technologies that make up the technology stack are all JS-based. Thus, if one knows JavaScript (and JSON), the backend, frontend, and database can be operated easily.
The MERN stack has several benefits, including managing client data, estimates, job production, scheduling, order fulfillment, shipment, invoicing, and finance, among others, all from a single application.
MERN stack developers are in high demand in the tech industry due to their ability to develop full-stack web applications. MERN stands for MongoDB, Express, React, and Node. js. These four technologies together allow developers to create powerful web applications from scratch with a single language – JavaScript.
