## 問題 Problem 你想在函數體中調用函數本身。 You want to call a function from within that same function. ## 方法 Solution 使用一個具名函數： With a named function: ~~~ ping = -> console.log "Pinged" setTimeout ping, 1000 ~~~ 在匿名函數中，使用@arguments.callee@： With an unnamed function, using @arguments.callee@: ~~~ delay = 1000 setTimeout((-> console.log "Pinged" setTimeout arguments.callee, delay ), delay) ~~~ ## 討論 Discussion 盡管`arguments.callee`允許在一個匿名函數中使用遞歸，并且在內存密集型的程序中可能會有優勢，但是具名函數依然有其用途，可以讓代碼更加清晰，容易維護。 While?`arguments.callee`?allows for the recursion of anonymous functions and might have the advantage in a very memory-intensive application, named functions keep their purpose more explicit and make for more maintainable code.
