What is JSFiddle?

Editorial review
JSFiddle is a popular online code editor that allows developers to write, test, and share front-end code snippets directly in their web browser. It supports HTML, CSS, and JavaScript, along with various pre-processors like HAML, SCSS, SASS, and PostCSS, and a wide array of JavaScript frameworks and libraries such as jQuery, React, Vue, Angular, D3, and many more. This makes it an invaluable tool for rapid prototyping, debugging, and demonstrating web development concepts without the need for a local development environment. The platform offers features like live code validation, auto-save, hot reloading for CSS and HTML, and code autocompletion with contextual awareness. Recent updates include a switch to the Monaco editor (used in VSCode) for an enhanced editing experience, AI code completion (beta) powered by the Codestral model, and a CSS Flexbox generator. JSFiddle is ideal for front-end developers, educators, and anyone looking to quickly experiment with web technologies or share runnable code examples.
