What does HTML5's use of polyfills mean? This term appears frequently in websites about HTML5, such as HTML5-Cross-Browser-Polyfills.
As a result, we are compiling all the shims, fallbacks, and polyfills in this section so that they can be inserted into browsers that do not already support HTML5.
Actually, I have no idea what polyfills are supposed to signify.
And what distinguishes shims, fallbacks, and polyfills from one another?
