JavaScript has come a long way since its inception, and it is ever-growing. MERN stack technologies have challenged the status quo and broken new ground for what is possible with JavaScript. But when it comes to developing real-world applications that need to be sustainable, is it a worthy choice? Some of the reasons that make a strong case for choosing MERN for your next web application are briefly outlined in the following sections.
Relevance of MERN
Consistency across the technology stack
As JavaScript is used throughout, developers don't need to learn and change gears frequently to work with very different technologies. This also enables better communication and understanding across teams working on different parts of the web application.
Takes less time to learn, develop, deploy, and extend
Consistency across the stack also makes it easy to learn and work with MERN, reducing the overhead of adopting a new stack and the time to develop a working product. Once the working base of a MERN application is set up and a workflow established, it takes less effort to replicate, further develop, and extend any application.
Widely adopted in the industry
Organizations of all sizes have been adopting the technologies in this stack based on their needs because they can build applications faster, handle highly diverse requirements, and manage applications more efficiently at scale.
Community support and growth
Developer communities surrounding the very popular MERN stack technologies are quite diverse and are growing on a regular basis. With lots of people continuously using, fixing, updating, and willing to help grow these technologies, the support system will remain strong for the foreseeable future. These technologies will continue to be maintained, and resources are very likely to be available in terms of documentation, add-on libraries, and technical support.
The ease and benefits of using these technologies are already widely recognized. Because of the high-profile companies that continue adoption and adaptation, and the growing number of people contributing to the code bases, providing support, and creating resources, the technologies in the MERN stack will continue to be relevant for a long time to come.
In order to determine whether this widely adopted stack will meet the specific requirements of your project, you can explore the extent of feature implementations possible with this group of technologies. In the next section, we will highlight a few aspects of this stack and also several features of the book's example applications that demonstrate the diverse array of options that are available with these technologies.
