* This is an Applicative Order Y-Combinator written in JavaScript. Y combinator is used to formally define recursion | |
* in languages that do not support it. JavaScript already does, but studying and understanding how this works | |
* is an enlightening experience anyway. | |
* | |
* Y and Yb are identical, just written differently - pick the one that's easier to read for you. An example is provided with | |
* factorial function. | |
