javascript - 在 For 循环上设置超时/延迟的问题

Question

您能否告诉我如何在以下代码上设置超时/延迟:

$(function() {
  var alpha = Array("a","b","c","d","e","f","g","h","i","j","k","l","m","z");

  for ( var i = 0; i < alpha.length; i++ ) {

      $("#box").html(alpha[i].toUpperCase());
}
});

这是一种方法:

$.each(alpha, function (_, letter) {
    $("#box").delay(500).queue(function (next) {
        $(this).html(letter.toUpperCase());
        next();
    });
});
