👉 An idempotent function is a mathematical function that has the property of being equal to itself repeatedly. In other words, if we have an idempotent function $f$, then for any two arguments $x$ and $y$, we have: $$ f(x) = f(y) \implies x = y $$ This means that the value of the function does not change when it is applied to itself repeatedly. This property is important in many areas, including computer science where idemp
