Server-side: It provides the necessary objects for a server to run JavaScript. For example, if server-side extensions allow a programme to interact with a database, give information continuity from one invocation of the application to another, or manipulate files on a server. These days, node.js is the most well-known and practical framework.
Imperative language: In this kind of language, our main focus is how something should be done. It only regulates the computation’s flow. The object-oriented approach and procedural programming approaches fall within this category. When using async await, we consider what needs to be done after the async call.
Declarative programming – In this kind of language, we are concerned with how things should be done, and logical computation is essentially needed. Here, describing the desired outcome is the major purpose rather than giving explicit instructions on how to get it, like the arrow function does.
