## Overview

jq-console is a jQuery terminal plugin: an application creates a console, requests input or a prompt, receives the user’s submitted text through a callback, and can write a result back to the console. Its runtime also supports queued operations, multiline prompts and indentation, history, keyboard shortcuts, matching delimiters, ANSI styling, and DOM output. The sampled implementation is a single JavaScript file; the internal responsibilities below are conceptual components within it. Relationships are supported by the README or the shown implementation excerpts.

Main entry points: [`lib/jqconsole.js`](https://github.com/replit-archive/jq-console/blob/master/lib/jqconsole.js) (Prompt operations)
