isomorphism
Abstract algebra: Take a group G, and a group H, with a group operation *. G is isomorphic to H if there exist a map f: G->H such that:1: f is
injective2: f is surjective3: f(a*b)=f(a)*f(b) for all a,b in GIf f satisfies these three
properties, f is called an isomorphism.

A
JavaScript application which can be executed in both a browser and a non-browser
runtime. This was the first term used to describe this concept, but "Universal JavaScript" now has wider acceptance. Mathematicians and functional programmers will scoff at you if you use "isomorphic" to describe JavaScript, so
save face by using "universal" instead.

In
category theory an isomorphism is a morphism between two (possibly equal) objects admitting a morphism in the opposite direction such that
composing the two morphisms in either order results in an identity morphism. Intuitively it is an
identification of one object with another.
