## Description

oxc is a high-performance JavaScript toolchain developed in Rust for parsing, transforming, and analyzing JavaScript and TypeScript source code. It provides a set of core utilities including a parser that converts code into an abstract syntax tree, a linter for identifying problematic patterns, a formatter for standardizing visual style, and a minifier for reducing production file sizes.

The project focuses on high-performance execution through a system design that utilizes single-pass parsing, zero-copy string slicing, and parallel worker processing to handle large codebases. It further optimizes efficiency using a biphasic syntax transformation model and lazy-loading module resolution.

The toolchain covers broad code analysis and transformation capabilities, including module path resolution and the ability to modify source code for different environments.
