如何为两个数组的内容创建每个唯一的组合？

function createUniqueCombinations(array1, array2) {
  var result = [];

  for (var i = 0; i < array1.length; i++) {
    for (var j = 0; j < array2.length; j++) {
      var combination = array1[i] + " " + array2[j];

      if (!result.includes(combination)) {
        result.push(combination);
      }
    }
  }

  return result;
}

// 示例用法
var array1 = [1, 2, 3];
var array2 = ["a", "b", "c"];
var combinations = createUniqueCombinations(array1, array2);
console.log(combinations);

[ "1 a", "1 b", "1 c", "2 a", "2 b", "2 c", "3 a", "3 b", "3 c" ]
