DevDocs is a great online documentations web app. However, sometimes you just want to simply look up a simple method without leaving the website you are currently reading to check out it intensively.
DevDocs Web Ext can just be used for your quick looking-up. You can quickly search for a function name, or any other things in devdocs.io, in a popup extension window.
Visit Chrome Web Store to install it.
