In most browsers the shorter and more specific variant of the code will run faster (in some instances much faster) than the second variant and so it makes sense to use the shorter and more specific version. It also makes the code easier to read and maintain.
In the United States and Canada frozen ice on a stick is generically referred to as a popsicle due to the early popularity of the Popsicle brand, and the word has become a genericized trademark to mean any ice pop or freezer pop, regardless of brand or format.
Frank Epperson of Oakland, California, popularized ice pops after patenting the concept of frozen ice on a stick in 1923. He initially called it the Epsicle. A couple of years later, Epperson sold the rights to the invention and the Popsicle brand to the Joe Lowe Company in New York City.
