Boa is an experimental JavaScript engine built in Rust that supports over 90% of the ECMAScript specification. It's designed for performance and compatibility, continuously improving its conformance to the evolving JavaScript standards. Users can test Boa in a live Wasm playground or through a command-line interface (CLI) using boa_cli. The project includes several components, or crates, such as boa_ast for the Abstract Syntax Tree, boa_engine for built-in objects and execution, and boa_parser for parsing JavaScript code. To get started, you simply need to add the boa_engine crate to your Cargo.toml file, along with a few lines of code in your main.rs. The example provided shows how to evaluate a simple JavaScript expression, demonstrating how straightforward it is to execute JavaScript using Boa. For those interested in contributing, the documentation outlines requirements, including having Rust installed and proper configurations for popular editors like VSCode. Boa offers various command-line options for running JavaScript files, including strict mode, AST dumping, and module handling. Users can benchmark Boa against other engines, with the current benchmarks derived from v8's suite. Local benchmarks can be run with a specific command, and users can modify Makefiles to customize which benchmarks to include. The project encourages community engagement, providing channels for questions and discussions through platforms like Matrix and Discord.
