For循环和While循环Javascript

Question

任何人都可以将此while循环转换为for循环。我会很感激的。

  var index = 0;

  while (true)

    log(index++);

Answer 1

这是一个简单的实现：var index = 0for (;;)  log(index++)

Answer 2

var x = true;for (var index = 0; x == true) { log(index++)}//if x is never set to false you could very quickly suffer a memory leak
