A **fixed-point combinator** is a higher-order function that computes the fixed point of other functions. In simpler terms, it allows you to find a point that satisfies the condition \\( f(x) = x \\) for a given function \\( f \\). This concept is particularly important in functional programming, recursion, and lambda calculus, where named functions may not always be available due to the nature of the constructs used.
