如何在数组中包含span标记？

function wrapWithSpan(arr) {
  var result = [];
  for (var i = 0; i < arr.length; i++) {
    var element = arr[i];
    if (typeof element === 'string') {
      result.push('<span>' + element + '</span>');
    } else if (typeof element === 'object') {
      var span = document.createElement('span');
      span.appendChild(element);
      result.push(span);
    }
  }
  return result;
}

// 示例用法
var originalArray = ['Hello', 'World', document.createElement('div')];
var newArray = wrapWithSpan(originalArray);
console.log(newArray);
