With this, JavaScript polyfills and conditional files may be loaded based on the detection of a given feature with the help of jQuery and the jQuery getScript method. Should this condition need to be retested, additional JavaScript would need to be included. Below Modernizr is checking for local storage support. This applies worldwide. What about the other HTML5 element projects? All front end developers have shared this frustration at one point or another. The shivCSS is true by default and can be set false, only before html5shiv. Understand, not all of these features need polyfills.
