Question

是否有办法将《一套规则》直接转换为“强权”(不首先将套件转换成阵列)? 我在Mozilla 上查阅了文件,我认为这些文件可能是这样做的一种方式。这是我做的:

let myset = new Set();
myset.add(3);
myset.add(" Wise ");
myset.add(" Men ");

let setStr = myset.toString();
let setArrStr = Array.from(myset).toString();

console.log("Set to String: " + setStr );  //"Set to String: [object Set]"
console.log("Set to Array to String: " + setArrStr);  // "Set to Array to String: 3, Wise , Men "

Answer 1

You can convert to string directly like so:

let string = "";
let myset = new Set();
myset.add(3);
myset.add(" Wise ");
myset.add(" Men ");

myset.forEach(value => string += value);
console.log(string); // → "3 Wise  Men "

Hope you got your answer.

Answer 2

或者说,通过阵列进行更多的契约......

let myset = new Set();
myset.add(3);
myset.add("Wise");
myset.add("Men");

console.log(Array.from(myset).join(  )); // → "3WiseMen"
console.log(Array.from(myset).join(   )); // → "3 Wise Men"
