Ya.. "Wouldn’t it be great if every javascript developer could experiment Lodash in the browser without needing to install anything or to create a JsFiddle?" ... Wouldn't it be great if you could do that with any NPM package? Oh ya, you can... https://npm.runkit.com/lodash ;D

runkit is server side. Therefore the evaluation is not instantaneous. Also, you cannot manipulate the DOM.
