What are the differences between MERN, MEVN, and PERN stacks, and when is MERN the right choice?

Clarifies stack differences (React vs Vue, NoSQL vs SQL) and when choosing MERN makes sense in modern web development.

• MERN uses React for frontend, MEVN uses Vue, and PERN replaces MongoDB with PostgreSQL. • Choose MERN for robust React ecosystem, rich component architecture, support for React Native, and strong job-market leverage. • For lighter projects or rapid prototyping, MEVN may be preferable; PERN suits relational-data-intensive applications.
