从javascript数组中提取包含唯一字符的字符串

function extractUniqueStrings(arr) {
  var uniqueStrings = [];

  for (var i = 0; i < arr.length; i++) {
    var string = arr[i];
    var charSet = new Set(string);

    if (charSet.size === string.length) {
      uniqueStrings.push(string);
    }
  }

  return uniqueStrings;
}

// 示例用法
var strings = ["hello", "world", "javascript", "cloud", "computing"];
var uniqueStrings = extractUniqueStrings(strings);
console.log(uniqueStrings);
