MERN Stack Web Development Roadmap for 60 Days:

Welcome to your journey to becoming a MERN stack developer! The MERN stack—MongoDB, Express.js, React, and Node.js—is a powerful, JavaScript-based technology stack for building modern, full-stack web applications.

 In just 60 days, this roadmap will guide you from the basics to advanced concepts, equipping you with the skills to create dynamic, scalable apps. Whether you’re a complete beginner or an intermediate learner looking to solidify your skills, this plan is for you. 

You’ll need about 4-6 hours daily—adjust based on your pace. By the end, you’ll have a portfolio-worthy project and the confidence to tackle real-world development. Let’s get started!
