Project Title

boa — An Embeddable JavaScript Engine in Rust

Overview

Boa is an experimental JavaScript lexer, parser, and interpreter written in Rust, designed to support over 90% of the latest ECMAScript specification. It is known for its continuous improvement in conformance to keep up with the evolving standard, making it a robust choice for embedding JavaScript in Rust applications.

Key Features

Supports over 90% of the latest ECMAScript specification.
Continuously improved conformance to ECMAScript standards.
Provides a live WASM playground for immediate testing and experimentation.
Offers a CLI tool boa_cli for command-line interaction.

Use Cases

Embedding JavaScript execution within Rust applications.
Providing a JavaScript environment for web assembly (WASM) applications.
Offering a REPL (Read-Eval-Print Loop) for interactive JavaScript execution.
Enabling the development of tools and applications that require JavaScript interoperability with Rust.

Advantages

Rust-based performance and safety benefits.
High conformance to ECMAScript, ensuring broad compatibility.
Active community and continuous development.
Provides a range of crates for modular usage in different parts of a project.

Limitations / Considerations

As an experimental engine, it may not be fully stable for all use cases.
May have some limitations in terms of supported ECMAScript features compared to more mature engines.
Requires Rust knowledge for integration and customization.

Deno: A secure JavaScript/TypeScript runtime built with V8, focuses on modern standards and security.
QuickJS: A small and embeddable JavaScript engine, with a focus on speed and low memory usage.
GraalVM: A high-performance runtime that provides significant improvements in application performance and efficiency, with support for JavaScript and other languages.
