What is JSFiddle?
JSFiddle is an online playground for front-end code. It has panels for HTML, CSS and JavaScript and shows the result live, so you can test an idea or reproduce a bug without setting up a project.
You can add libraries and frameworks, use preprocessors like SCSS or TypeScript, and save a fiddle to share a link.
