Course Introduction:JavaScript does not support tail recursion. Tail recursion is an algorithm optimization technique that converts recursive algorithms into more efficient iterative algorithms. Compared with conventional recursion, tail recursion can greatly reduce the depth of the stack, thereby avoiding problems such as stack overflow. However, JavaScript does not support tail recursion, which is a problem for many engineering practices. Why doesn't JavaScript support tail recursion? In many programming languages, tail-recursive operations are automatically optimized into iterative operations by the interpreter or compiler. This is achieved through certain optimization techniques

Course Introduction:The tail recursion optimization strategy effectively reduces the function call stack depth and prevents stack overflow by converting tail recursive calls into loops. Optimization strategies include: Detect tail recursion: Check whether there are tail recursive calls in the function. Convert functions into loops: Use loops instead of tail-recursive calls and maintain a stack to save intermediate state.

Course Introduction:Recursive definition and optimization: Recursive: A function calls itself internally to solve difficult problems that can be decomposed into smaller sub-problems. Tail recursion: The function performs all calculations before making a recursive call, which can be optimized into a loop. Tail recursion optimization condition: recursive call is the last operation. The recursive call parameters are the same as the original call parameters. Practical example: Calculate factorial: The auxiliary function factorial_helper implements tail recursion optimization, eliminates the call stack, and improves efficiency. Calculate Fibonacci numbers: The tail recursive function fibonacci_helper uses optimization to efficiently calculate Fibonacci numbers.

Course Introduction:Tail recursion optimization (TRO) improves the efficiency of certain recursive calls. It converts tail-recursive calls into jump instructions and saves the context state in registers instead of on the stack, thereby eliminating extra calls and return operations to the stack and improving algorithm efficiency. Using TRO, we can optimize tail recursive functions (such as factorial calculations). By replacing the tail recursive call with a goto statement, the compiler will convert the goto jump into TRO and optimize the execution of the recursive algorithm.

Course Introduction:Tail recursive calls do not create a new function stack frame, and recursive calls can be optimized to avoid stack space exhaustion. In the actual case, the factorial calculation function was optimized by introducing an auxiliary function to convert the original recursive call into a tail recursive call.
