QuickJS vs Scala.js: What are the differences?

Introduction: When comparing QuickJS and Scala.js, it is essential to understand the key differences between these two technologies for web development.

1. Runtime Environment: QuickJS is a small and efficient JavaScript engine that supports ES2019 features and is designed for embedding in various applications. On the other hand, Scala.js is a compiler that allows developers to write Scala code and have it compiled to JavaScript, providing a seamless transition between the two languages.

2. Language Compatibility: QuickJS primarily focuses on JavaScript and its features, making it a suitable choice for projects that heavily rely on JavaScript. In contrast, Scala.js enables developers to utilize Scala's advanced language features, such as functional programming, while still benefiting from JavaScript interoperability.

3. Performance: QuickJS is known for its fast startup time and low memory footprint, making it suitable for projects where these factors are critical. Scala.js, while offering powerful language capabilities, may have a slightly higher overhead due to the Scala-to-JavaScript compilation process.

4. Community and Ecosystem: QuickJS has a growing community of developers but may not have as extensive an ecosystem as other JavaScript frameworks. Scala.js, being part of the Scala ecosystem, benefits from a large and active community, with access to libraries and tools that enhance productivity and development capabilities.

5. Compilation Process: QuickJS does not require a separate compilation step as it operates as an interpreter, making it easy to integrate into existing projects. In contrast, Scala.js involves a compilation process that translates Scala code to optimized JavaScript, ensuring type safety and correctness at compile time.

6. Type System: QuickJS is dynamically typed, allowing for flexibility in development but potentially leading to runtime errors. Scala.js, being statically typed, provides strong type safety guarantees at compile time, helping developers catch errors early in the development process.

In Summary, QuickJS and Scala.js differ in their runtime environment, language compatibility, performance, community support, compilation process, and type system, offering developers a choice between efficiency and advanced language features.

Detailed Comparison

Scala.js	QuickJS
It is a safer way to build robust front-end web applications. With it, typos and type-errors are immediately caught and shown to you in your editor, without even needing to compile your code. Refactor any field or method with ease, with the confidence that if you mess it up the editor will tell you immediately	It supports the ES2019 specification including modules, asynchronous generators and proxies. It optionally supports mathematical extensions such as big integers (BigInt), big floating point numbers (BigFloat) and operator overloading.
Strong typing; optimizes your Scala code into highly efficient JavaScript; use any JavaScript library right from your Scala.js code	Small and easily embeddable; no external dependency; Fast interpreter

What are some alternatives to Scala.js, QuickJS?

Babel

Babel will turn your ES6+ code into ES5 friendly code, so you can start using it right now without waiting for browser support.

Modernizr

It’s a collection of superfast tests or detects as we like to call them which run as your web page loads, then you can use the results to tailor the experience to the user. It tells you what HTML, CSS and JavaScript features the user’s browser has to offer.

Rome

It is a linter, compiler, bundler, and more for JavaScript, TypeScript, JSON, HTML, Markdown, and CSS. It is designed to replace Babel, ESLint, webpack, Prettier, Jest, and others. It unifies functionality that has previously been separate tools. Building upon a shared base allows us to provide a cohesive experience for processing code, displaying errors, parallelizing work, caching, and configuration.

Rome

It is an experimental JavaScript toolchain. It includes a compiler, linter, formatter, bundler, testing framework and more. It aims to be a comprehensive tool for anything related to the processing of JavaScript source code.

Hermes

It is a JavaScript engine optimized for fast start up of React Native apps on Android. It features ahead-of-time static optimization and compact bytecode.

Sucrase

Sucrase is an alternative to Babel that allows super-fast development builds. Instead of compiling a large range of JS features down to ES5, Sucrase assumes that you're targeting a modern JS runtime (e.g. Node.js 8 or latest Chrome) and focuses on compiling non-standard language extensions: JSX, TypeScript, and Flow.

Emscripten

This allows applications and libraries originally designed to run as standard executables to be integrated into client side web applications.

Fable.io

It is a compiler powered by Babel designed to make F# a first-class citizen of the JavaScript ecosystem.
