The goals 💪🏻Pure Functions & Side Effects ✌🏻Factory Functions 👍🏻Closures (& Scope Revisited) 👊🏻Recursion Pure vs Impure functions Pure functions In simple terms, pure functions do not have an internal state. Therefore, all operations performed in pure functions are not affected by their state. As a result, the same input parameters will give the same deterministic output regardless of how many t..
