Companies that use RxJS
RxJS is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. This project is a rewrite of Reactive-Extensions/RxJS with better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface.

RxJS is a popular library for reactive programming using Observables, which makes it easier to compose asynchronous or callback-based code. It is commonly used in JavaScript applications to handle events, manage asynchronous operations, and work with streams of data. RxJS provides a set of tools for creating and manipulating observables, allowing developers to write more concise and readable code when dealing with complex asynchronous operations.
RxJS falls under the category of Concurrency Frameworks, which are tools and libraries that help manage the flow of concurrent tasks and processes in software applications. In the context of RxJS, it specifically focuses on managing asynchronous events and data streams in reactive programming paradigms. By using observables, RxJS enables developers to handle events and data streams as first-class citizens in their applications, leading to more responsive and maintainable codebases.
Founded in 2015 by Microsoft and open-sourced under the ReactiveX organization, RxJS was initially motivated by the need for a robust reactive programming library for JavaScript. The ReactiveX project aims to provide a consistent way to handle asynchronous data streams across different programming languages, with RxJS being the implementation for JavaScript. Since its inception, RxJS has gained significant traction in the developer community due to its powerful features and ease of use.
Currently, RxJS maintains a strong market share within the Concurrency Frameworks category, with many JavaScript developers relying on it for handling reactive programming tasks. As the demand for reactive and responsive web applications continues to grow, it is expected that RxJS will maintain or even increase its market share in the future. With ongoing updates and improvements, RxJS remains a key player in the realm of reactive programming in JavaScript applications.
