functional programming – What is a y-combinator? – Stack …
A Y-combinator is a functional (a function that operates on other functions) that enables recursion, when you can’t refer to the function from within itself. In computer-science theory, it generalizes recursion, abstracting its implementation, and thereby separating it from the actual work of the function in question.
The Y combinator. The Y combinator is the same as the Z combinator, except that it does not wrap the (self-apply self) call in a lambda, conveniently delaying evaluation. This only works in lazy languages though, like Haskell, where functions evaluate their arguments only when needed, and not before executing the body.
The lazy Y combinator is often referred to as the normal-order Y combinator and the strict one is referred to as the applicative-order Y combinator. Basically, normal-order is another way of saying lazy and applicative-order is another way of saying strict.

10/30/2019 · Explanation of the above quote: Paul Graham, a computer scientist, wanted to invest in entrepreneurs who are also programmers (“ hackers ” ).So he named his investing firm “ Y Combinator ”, which is a computer science (programming) concept, in order to attract hackers.
Y Combinator introduced the safe (simple agreement for future equity) in late 2013, and since then, it has been used by almost all YC startups and countless non-YC startups as the main instrument for early-stage fundraising.
In 2005 Y Combinator held its first Demo Day. Eight companies showed off their products and sold their vision to an audience of about 15 investors. Today, accelerators and incubators around the world hold their own demo days, and in 2016 over 200 YC companies will.
