At times, Node.js can feel like a black box. Shifting to an asynchronous programming model changes how developers are required to handle and interpret existing data. There are many solutions out there to help the users gain more visibility; however, it has been proved that all those solutions out there to capture such critical information come with a high toll on the performance of every application implementing them.

Sometimes an application needs more than Node.js to develop and bootstrap itself. Maybe the project needs some automation from a different programming language than JavaScript; even in that scenario, Node.js can run those required tasks; with that, your whole application could be easier to maintain and won’t have a lot of technologies mixed in the same project.
