Tutorial: ink

Ink is a library for building interactive command-line interfaces using React. It mirrors the browser environment by providing a custom DOM (powered by the Yoga layout engine), a Reconciler to translate React state into terminal operations, and a specialized Renderer that paints the UI to stdout using efficient diffing to ensure high performance and prevent flickering.
