Tail recursion optimizes recursive functions to prevent stack overflow by allowing the same stack frame to be reused for each call, enhancing memory efficiency.
In plain recursion, each call generates a new stack frame which can lead to a stack overflow as the recursion depth increases; tail recursion circumvents this.
A function is tail-recursive when the recursive call is the last operation executed, enabling the compiler to optimize recursive calls effectively.
The ability of tail recursion to maintain stack safety is crucial for writing scalable recursive functions, offering programmers a vital tool in functional programming.
