MERN stack is essential in 2023 and in high demand because of its wide application in the web development community. It is used for its ease and dynamic nature. Additionally, the MERN stack is the complete package that features both front and back-end development.
Any front or back-end developer looking to transition into full-stack can begin with the MERN stack. It is in high demand because of its simplicity and scalability. Additionally, it requires the use of JavaScript across all of its programs. A front-end developer would have relative ease as they are already familiar with the programming language. A back-end developer can also transition easily because the MERN stack supports three back-end development tools for faster computing. In addition to the ease of transition, there is substantial community backing for all the tools. All the open-source programs are widely popular irrespective of their place in the MERN stack. The applicability of these programs helps in creating a community which would aid and assist when you hit a wall during a project. For employers, the MERN stack is in high demand because it reduces the need for varied expertise and requires the knowledge of JavaScript and the four programs in MERN.
The back end is the next step towards learning the MERN stack. Except for React, the remaining three components help in back web development. Node.js helps in the scalability and performance of the website. It also helps make the application run faster as it itself is based on the Chrome V8 engine. While NodeJS is used for complex projects, Express.js is used for single-page apps. It allows for simplicity and complexity without having to switch stacks. Express.js works with Node.js and has key features like an application programming interface and lightweight architecture. If efficiency is the priority, Node.js and Express.js are extremely helpful. Databases are crucial in back-end development because the website needs to return meaningful data while running at high speeds. Database management is an aspect of back-end web development which deals with accessing and storing data. MongoDB is a database system which is based on NoSQL. The main benefit of using MongoDB is that it can deal with large amounts of data with ease. It means that the size of the project will not prove to be a hindrance while using MongoDB.
