let str = "Hello,World,From,JavaScript";
let parts = str.split(","); // 使用逗号作为分隔符
console.log(parts); // 输出: ["Hello", "World", "From", "JavaScript"]

let strWithLimit = "one,two,three,four,five";
let limitedParts = strWithLimit.split(",", 3); // 只分割前三个元素
console.log(limitedParts); // 输出: ["one", "two", "three"]

console.log(parts); // 输出: ["one", "two", "three"]

  let parts = str.split(",");
} else {
