## Description

CoffeeScript is a source-to-source transpiler that transforms a concise high-level syntax into standard JavaScript. It enables the development of logic for web applications and server-side environments by converting source code into a format compatible with browsers and server runtimes.

The project provides a workflow for rapid prototyping and script execution automation, allowing users to run source files through a compiler and execute the resulting code immediately without a manual build step.

The tooling leverages lexical analysis and abstract syntax tree transformations to manipulate code constructs before final output. It includes a command line interface and an in-memory compilation pipeline to facilitate the transition from source code to executable JavaScript.
