let’s start with understanding what is a technology stack; a tech stack is the combination of technologies used to create a web application. Any web application is usually made using multiple technologies (frameworks, libraries, databases, etc). Also called a solutions stack, technology infrastructure, or a data ecosystem.
Eg, The MERN stack includes four open-source components: MongoDB, Expressjs, Reactjs, and Nodejs. These components provide an end-to-end framework for developers to work in.
Another popular question is the difference between the MERN & MEAN stack; the MERN stack is an updated version of the MEAN stack, where It uses React.js instead of Angular.js. The main purpose of React is to be fast, scalable, and simple.
MERN is designed to make the development process smoother and easier. Here’s an example of a popular application written in Node.js
Netflix is the world’s leading provider of streaming media and video-on-demand. It’s a data-driven platform that uses a massive amount of A/B testing to build a rich experience for its millions of subscribers worldwide. Great numbers of unique packages every push cycle create a problem of conditional dependencies and app scalability. That’s why the company decided to leverage the lightweight and fast Node.js. One of the most important results of this was a 70-percent reduction in startup time.
MERN stack is a lot more flexible, the development is less time-consuming and as a result, you get fast and reliable software. Here’s another example;
