What is Reactive JavaScript?

7 min readJun 19, 2022

Before tackling Reactive JS, let’s review the Observer design pattern. Observer design patterns are a way of interacting with the world in a declarative manner. By using streams, you can easily achieve declarative dynamic behavior. Streams are variables marked with a $ symbol. For example, a variable named C$ concatenates the values of streams A and B. When a new value is pushed onto A, C$ reacts to that change.

Reactive javascript
When creating an application with complex computations, Reactive JS is an excellent choice. If you are using state machines, RxJS is ideal for that. But if you need a more flexible implementation, write your own code instead. Luckily, there are some libraries that can help you get started with Reactive JS. In this article, we will discuss a few of them. Also, we’ll cover some of the benefits of RxJS.

Using a reactive programming paradigm is a good choice for many types of applications. Big data, event-heavy webapps, and microservices are all excellent uses for it. Reactive libraries provide utility methods that make it easy to manage this event flow. It can also handle asynchronous events. In short, Reactive JS is an excellent choice for applications whose data flow is constantly in flux. However, if you’re using it for something else, you need to take some precautions to ensure that it stays in place.
