What is the meaning of polyfills in HTML5? I saw this word in many sites about HTML5, e.g. HTML5-Cross-Browser-Polyfills.
So here we’re collecting all the shims, fallbacks, and polyfills
in order to implant HTML5 functionality in browsers that don’t
natively support them.
I actually don’t understood what is the meaning of polyfills.
Is it a new HTML5 technique or a JavaScript library? I never heard this word before HTML5.
And what is the difference between shims, fallbacks, and polyfills?
