Highland.js vs RxJS: What are the differences?

Introduction

Highland.js and RxJS are both libraries that deal with asynchronous and event-based programming in JavaScript. However, they have some key differences that set them apart.

Execution Model: Highland.js uses lazy evaluation, which means that operations are only executed when the consumer asks for data. On the other hand, RxJS uses eager evaluation, where operations are executed as soon as they are defined.
Error Handling: Highland.js treats errors as values and allows you to work with them in a functional way, while RxJS treats errors as exceptions and handles them through try/catch blocks or error callbacks.
Interoperability: RxJS has better support for interop with other libraries and frameworks, such as Angular, React, and Vue.js, due to its popularity and widespread adoption in the community. Highland.js, while powerful, may have limited integration with other tools.
Syntax: Highland.js follows a more functional programming style, emphasizing on chaining functions and composing operations together. RxJS, on the other hand, provides a more object-oriented approach with a rich set of methods chained on observable sequences.
Community Support: RxJS has a larger community and ecosystem, with more resources, tutorials, and extensions available. This can be advantageous when looking for help, learning new features, or finding solutions to common problems.
Performance: In terms of speed and efficiency, RxJS tends to be faster and more optimized due to its wide usage and constant development. Highland.js, while performant, may not have the same level of optimizations and enhancements.

In Summary, Highland.js and RxJS differ in their execution model, error handling, interoperability, syntax, community support, and performance.

Detailed Comparison

RxJS	Highland.js
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.	It manages synchronous and asynchronous code easily, using nothing more than standard JavaScript and Node-like Streams. You may be familiar with Promises, EventEmitters and callbacks, but moving between them is far from seamless.
-	Intended to work with node.js(or browserify) environment which is really nice; No alien concepts(from JavaScript/Node perspective); Back-pressure; The implementation is on top of Node streams which is really great idea; Small footprint

What are some alternatives to RxJS, Highland.js?

Underscore

A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

Deno

It is a secure runtime for JavaScript and TypeScript built with V8, Rust, and Tokio.

Akka

Akka is a toolkit and runtime for building highly concurrent, distributed, and resilient message-driven applications on the JVM.

Orleans

Orleans is a framework that provides a straightforward approach to building distributed high-scale computing applications, without the need to learn and apply complex concurrency or other scaling patterns. It was created by Microsoft Research and designed for use in the cloud.

Chart.js

Visualize your data in 6 different ways. Each of them animated, with a load of customisation options and interactivity extensions.

Immutable.js

Immutable provides Persistent Immutable List, Stack, Map, OrderedMap, Set, OrderedSet and Record. They are highly efficient on modern JavaScript VMs by using structural sharing via hash maps tries and vector tries as popularized by Clojure and Scala, minimizing the need to copy or cache data.

Netty

Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server.

Finagle

Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers. Finagle implements uniform client and server APIs for several protocols, and is designed for high performance and concurrency.

Lodash

A JavaScript utility library delivering consistency, modularity, performance, & extras. It provides utility functions for common programming tasks using the functional programming paradigm.

Ramda

It emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code.
