• A JavaScript library that detects the features available in a user’s browser. This lets web pages avoid unsupported features by informing the user their browser is not supported or loading a polyfill. Modernizr aims to provide feature detection in a consistent and easy to use manner that discourages the use of failure-prone browser sniffing. Modernizr was first released in 2009, and last updated in 2017. ← Wikipedia ↑ modernizr.com
