What distinguishes MERN, MEVN, and PERN stacks—and when is MERN the most appropriate choice in 2025?

Clarifies differences across front-end frameworks (React vs Vue) and backend databases (NoSQL vs SQL), highlighting strategic use cases.

• MERN (MongoDB, Express, React, Node.js) uses React; MEVN swaps React for Vue; PERN replaces MongoDB with PostgreSQL. • MERN is ideal when leveraging React’s ecosystem, React Native compatibility, and robust community support. • MEVN suits prototyping and lightweight projects; PERN is better for schema-driven, relational-data-centric apps.
