A MERN stack developer and a MEAN stack developer are both full-stack web developers who use different sets of technologies to build web applications.
A MERN stack developer uses MongoDB, Express.js, React.js, and Node.js to build web applications. MongoDB is a NoSQL database, Express.js is a back-end web framework, React.js is a JavaScript library for building user interfaces, and Node.js is a JavaScript runtime for building server-side applications. Together, these technologies form the MERN stack, which is a popular technology stack for building modern web applications.
A MEAN stack developer uses MongoDB, Express.js, AngularJS and Node.js to build web applications. MongoDB is a NoSQL database, Express.js is a back-end web framework, AngularJS is a JavaScript framework for building dynamic web applications, and Node.js is a JavaScript runtime for building server-side applications. Together, these technologies form the MEAN stack, which is also a popular technology stack for building modern web applications.
The main difference between MERN and MEAN stack is the front-end framework, React.js is more popular and widely used these days and has better flexibility, performance and scalability compared to AngularJS. MERN stack developer also has an advantage in terms of being proficient in latest web technologies as compared to MEAN stack developer.
