An embeddable code editor written in JavaScript that matches the features and performance of native editors.

Ace is a standalone, embeddable code editor implemented in JavaScript. It aims to provide functionality and performance comparable to native editors like Sublime Text, Vim, and TextMate within a web browser. Ace utilizes the DOM for rendering and supports syntax highlighting for over 120 languages, customizable themes, automatic indentation, and keybindings (including Vim and Emacs modes). It can handle large documents and offers features such as search and replace with regular expressions, code folding, multiple cursors, and live syntax checking. Ace is suitable for integrating into web applications, IDEs, and online coding environments, enhancing the user experience with advanced code editing capabilities.

2. Create a DOM element (e.g., a div) to host the editor: <div id="editor"></div>.
3. Initialize the Ace editor using JavaScript: var editor = ace.edit("editor");.
4. Set the editor theme: editor.setTheme("ace/theme/monokai");.
5. Set the language mode (syntax highlighting): editor.session.setMode("ace/mode/javascript");.
6. Configure editor options as needed, such as font size or tab size: document.getElementById('editor').style.fontSize='12px';
7. Use editor.getValue() and editor.setValue() to interact with the code content.
