What is tail call optimization in recursive functions and how is it handled in ES6?
- Tail call optimization is a technique where the JavaScript engine optimizes recursive functions to avoid stack overflow errors. In ES6, tail call optimization is not explicitly mandated, but certain engine implementations may provide it.
- Tail call optimization in ES6 can be achieved through the use of proper coding practices, such as making the recursive call the last operation in the function and ensuring no additional processing is performed after the recursive call.
- ES6 introduces the concept of proper tail calls (PTC), allowing some recursive functions to be optimized for tail calls. This optimization is not universally supported across all JavaScript engines.
- Tail call optimization is automatically applied to all recursive functions in ES6, ensuring that stack overflow errors are mitigated, and the recursive calls are optimized for better performance.
Proper tail calls in ES6 involve making the recursive call the last operation in a function. While not all recursive calls benefit from tail call optimization, adhering to PTC principles can enhance performance in situations where tail call optimization is applied.
