## Summary Now that bumpalo has been inlined into oxc_allocator (#18168), this PR cleans up comments and documentation that still reference bumpalo as an external dependency. - Update module docs in `bump.rs` and `bumpalo_alloc.rs` to say "originally derived from" instead of "ported from" - Remove obsolete comments about bumpalo version pinning in `from_raw_parts.rs` - Update inline comments in `allocator.rs` from "delegates to bumpalo" to "it's a small function" - Remove outdated TODO about replacing bumpalo in `tracking.rs` - Update `ARCHITECTURE.md` and parser docs to reference `oxc_allocator` instead of bumpalo - Clean up bumpalo references in other crates (`oxc_semantic`, `oxc_data_structures`, `apps/oxlint`, `napi/parser`, `tasks/ast_tools`) ## Test plan - [x] `cargo check -p oxc_allocator` passes - [x] `cargo test -p oxc_allocator` passes - [x] Changes are documentation/comment only - no functional changes 🤖 Generated with [Claude Code](https://claude.ai/code)

🏗️ Design Principles
- Performance: Through rigorous performance engineering.
- Correctness: Through conformance testing to standards and similar projects.
- Developer Experience: Clear APIs, comprehensive documentation, and sensible configuration.
- Modular composability: Use individual components independently or compose them into complete toolchains.

⚡️ Quick Start
Linter
The production-ready linter catches mistakes for you with sensible defaults and optional configuration:
npx oxlint@latest
To give you an idea of its capabilities, here is an example from the vscode repository, which finishes linting 4800+ files in 0.7 seconds:
Formatter
Fast, opinionated code formatter compatible with Prettier:
npx oxfmt@latest
Parser (Node.js)
The fastest JavaScript/TypeScript parser written in Rust:
npm install oxc-parser
import { parseSync } from "oxc-parser";
const result = parseSync("const x = 1;");
Transformer (Node.js)
TypeScript, React, and modern JavaScript transformation:
npm install oxc-transform
import { transform } from "oxc-transform";
const result = transform("source.tsx", code, { typescript: true });
Minifier (Node.js)
High-performance JavaScript minifier:
npm install oxc-minify
import { minify } from "oxc-minify";
const result = minify(code, { mangle: true });
Rust
Individual crates are published for building your own JavaScript tools:

oxc = "0.x"
