What are the differences between MERN, MEVN, and PERN stacks—and why choose MERN?

Explains stack structure differences focusing on frontend frameworks (React vs Vue) and database types (NoSQL vs SQL).

• MERN uses React on the frontend and MongoDB backend; MEVN swaps React for Vue; PERN uses PostgreSQL instead of Mongo. • MERN is preferred for its strong React ecosystem, React Native compatibility, and wide developer support. • MEVN fits prototyping and lightweight apps better, while PERN is ideal for relational data needs and SQL-heavy workloads turn0search19.
