Nettet14. jun. 2012 · The existence of a Y combinator in JavaScript should imply that every JavaScript function has a fixed point (since for every function g, Y (g) and g (Y (g)) should be equal). However, it isn't hard to come up with functions without fixed points that violate Y (g) = g (Y (g)) (see here ). Even certain functionals do not have fixed points (see ... Nettet11. Putting it very simply, a fixed point is a point that, when provided to a function, yields as a result that same point. The term comes from mathematics, where a fixed point (or fixpoint, or "invariant point") of a function is a point that won't change under repeated application of the function. Say that we have function f ( x) = 1 / x.
