Feature Detection vs JavaScript Polyfills
Developers should use feature detection when building web applications that need to work across multiple browsers and devices with varying capabilities, such as in responsive web design or progressive web apps meets developers should learn and use polyfills when building web applications that need to support older browsers, such as internet explorer or legacy versions of chrome and firefox, to ensure cross-browser compatibility. Here's our take.
