What is MERN Stack?
Have you heard about the combination of numerous spices and ingredients to cook a delicious meal? MERN Stack creates similar magic to your website!

Every website is a result of a mixture of front-end and back-end development. While front-end development requires in-depth knowledge of HTML, CSS, JavaScript, and ReactJS, back-end development deals with database management and other tasks associated with server-side technology!

MERN stack developers have a thorough understanding of website and web application development. Here is a list of the four technologies comprising the MERN Stack.

MongoDB (best platform to collaborate on website development with ExpressJS, ReactJS, and NodeJS)
ExpressJS (contains small models for unbiased and simple server-side technology development)
ReactJS (for complex interface creation with linking data components to the back-end server)
NodeJS (back-end JavaScript run-time environment and platform to run ExpressJS)
