What is the importance of the MERN Stack Developer Assessment?
MERN stack is one of the most preferred user-oriented JavaScript stacks for deploying full-stack web applications efficiently. MERN is an updated variant of the MEAN stack that relies on using the ReactJS front-end development framework. Being a full-stack solution, MERN follows the three-tier web architecture comprising the database tier (MongoDB), application tier (ExpressJS and NodeJS), and front-end display tier (ReactJS).
MERN developers are primarily responsible for designing and developing front-end web applications and writing testable, high-quality, and reusable code. They translate design wireframes into fully functional web applications. Their work involves coordinating with development teams and managers to brainstorm software solutions. These developers are integral to design discussions, project planning, scheduling, addressing and resolving any technical issues should the need arise.
