What are the key differences between MERN, MEVN, and PERN stacks—and when should you choose MERN?

Compares stack choices (React vs Vue; MongoDB vs PostgreSQL) and outlines use cases where MERN is advantageous.

• MERN uses React, MEVN uses Vue, and PERN uses PostgreSQL as the database. • Choose MERN for rich component architecture, compatibility with React Native, and strong market-driven ecosystem. • MEVN shines for lightweight and rapid prototyping. PERN is ideal for structured relational data needs in enterprise settings. Tags: mern-stack, mevn-stack, pern-stack, javascript, react, vue
