What is Vanilla JavaScript Online Code Editor?

Built without external plugins, it offers features like syntax highlighting, auto-compile with output, working TAB spacing, and auto-brackets. It also includes infinite loop prevention for JavaScript execution and a code sharing ability via URL encoding. The editor uses `sessionStorage` for auto-save, meaning code is saved locally to the browser and not across machines.

FAQs

What programming languages does the online editor support?

The online code editor is specifically designed to support JavaScript, HTML, and CSS. It provides syntax highlighting and execution for these core web development languages, making it suitable for frontend projects and learning.

How does the code sharing feature work?

Code sharing is implemented by encoding the current content of the textarea into the URL hash. When someone accesses the URL with the encoded hash, the editor automatically loads that code, allowing for easy sharing of snippets.

Is my code saved automatically, and where is it stored?

Yes, the editor features an auto-save function that uses `sessionStorage`. This means your code is saved locally within your browser's session. However, it will not persist across different machines or if your browser clears its session storage.
