🖥️ Simple Terminal Made in JavaScript

A lightweight, embeddable terminal interface written in plain JavaScript. It simulates a command-line experience in the browser, complete with basic commands, command history, blinking cursor, and keyboard input.

The goal of this project isn't to create a fully working terminal with all features, rather a super simple terminal environment that can be added for fun anywhere, for whatever reason.

✨ Features

• Interactive terminal prompt
• Adding custom commands
• Command history (with arrow key navigation)
• Simulated blinking cursor
• Easily embeddable in any HTML page

Commands available as of now
