Node.js is a powerful tool for building modern web applications and has become an essential piece of technology for many developers and companies. According to the StackOverflow survey from 2022, NodeJS is the most common web technology used by professional programmers (46.31%) and those learning to code (52.86%). Developers and businesses love it for its asynchronism. In practice, the application can run on multiple threads and is highly scalable.

Node.js is an open-source, cross-platform runtime environment built on Chrome's V8 JavaScript engine. So, it can be used for, backend, frontend, or paired up with other technology (for example, with PHP on the frontend). The technology has a vast ecosystem of modules and packages available through the Node Package Manager (NPM), which allow your application to function more easily and reuse codes from other developers.

Node.js is widely used for building enterprise-grade software that can continuously run in the background and for developing web applications, APIs, microservices, and command-line tools. What is more, it has become one of the most popular server-side development technologies that successfully delivers information tailored for individual users.

Node.js is the perfect app prototyping tool. You can quickly write a working code without involving frameworks and unnecessary libraries. You can also quickly create and test every MVP (Minimum Viable Product) on the market. This can be a significant cost-saving measure for businesses, especially startups or small businesses with limited budgets.

Node.js has a large and active community of programmers who contribute to its development and create new libraries and modules. In that, a wide variety of tools and resources are already available to developers. This makes Node.js an ideal choice for businesses that need to handle high volatility, where there is no time for a long app’s deployment.

This technology is also perfect in building scalable cloud-native applications and reducing costs using a pay-as-you-go billing model (Functions-as-a-Service). For instance, Google Cloud makes available SDKs, in-IDE assistance, and native runtime support on Cloud Run, Cloud Functions that facilitate implementation and maintenance of Node.js applications.

JavaScript can be used on both frontend and backend. What is more, it is a widely used programming language that most developers are already familiar with. Therefore, full-stack developers can be hired for a project based on Node.js. They have the full set of skills required to independently handle the entire application project. In practice, it means those programmers always will have some tasks to do, or they can easily replace colleagues who are temporarily absent.
