Node.js is a powerful way to run JavaScript on a server. Node.js includes many core libraries (modules) for performing routine tasks. Node.js package managers, like npm and Yarn, make it simple for developers to leverage millions of useful modules, such as Gulp, Axios, and Dotenv.
Despite its versatility and robustness, Node.js isn’t capable of doing everything. Since Node.js isn’t suitable for CPU-intensive applications, you’ll need to add another technology to your tech stack to handle software that needs to compute and process a lot of data (e.g., augmented reality or video processing). There are already some attempts to implement JavaScript coding in applications that require significant computational loads, such as TensorFlow.js for machine learning models. However, they’re still in the early stages of adoption by the developer community.
