QuickJS vs Emscripten: What are the differences?

QuickJS: A small and embeddable JavaScript engine. 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; Emscripten: An Open Source LLVM to JavaScript compiler. This allows applications and libraries originally designed to run as standard executables to be integrated into client side web applications.

QuickJS and Emscripten can be primarily classified as "JavaScript Compilers" tools.

Some of the features offered by QuickJS are:

Small and easily embeddable
no external dependency
Fast interpreter

On the other hand, Emscripten provides the following key features:

Compile C and C++ code into JavaScript
Compile any other code that can be translated into LLVM bitcode into JavaScript
Compile the C/C++ runtimes of other languages into JavaScript

Emscripten is an open source tool with 17.9K GitHub stars and 2.12K GitHub forks. Here's a link to Emscripten's open source repository on GitHub.

What are some alternatives to Emscripten, 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.

Scala.js

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

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.
