如何在没有嵌套循环的情况下使用另外两个集合的内容创建新的对象集合

function createNewCollection(collection1, collection2) {
  var newCollection = [];

  for (var i = 0; i < collection1.length; i++) {
    var element1 = collection1[i];

    for (var j = 0; j < collection2.length; j++) {
      var element2 = collection2[j];

      var newObj = {
        property1: element1,
        property2: element2
      };

      newCollection.push(newObj);
    }
  }

  return newCollection;
}

// 示例用法
var collection1 = [1, 2, 3];
var collection2 = ['a', 'b'];

var result = createNewCollection(collection1, collection2);
console.log(result);

[
  { property1: 1, property2: 'a' },
  { property1: 1, property2: 'b' },
  { property1: 2, property2: 'a' },
  { property1: 2, property2: 'b' },
  { property1: 3, property2: 'a' },
  { property1: 3, property2: 'b' }
]
