If you’re tired of writing tooling around projects in Bash, take a look at Deno.

Deno is a modern “all-in-one” JS/TS platform that runs from a single binary without Node/npm. It has built-in support for formatting, linting, testing, benchmarking, coverage, hot-reload, and compilation into a standalone CLI.

Advantages: zero installation and reproducible dependencies, a secure sandbox with granular permissions, cross-platform compatibility, calling external processes via Deno.Command (convenient for wrapping Go/Rust/Python/Java), support for npm packages, FFI/WASM for integration with native code, and the ability to distribute utilities without a JS/TS stack via deno compile.
