有没有一个Javascript方法可以实现嵌套括号的连接？

function concatenateNestedBrackets(input) {
    let result = '';
    let stack = [];
    let currentString = '';

    for (let i = 0; i < input.length; i++) {
        let char = input[i];
        if (char === '(') {
            if (currentString) {
                stack.push(currentString);
                currentString = '';
            }
            stack.push(char);
        } else if (char === ')') {
            if (currentString) {
                stack.push(currentString);
                currentString = '';
            }
            let temp = '';
            while (stack.length && stack[stack.length - 1] !== '(') {
                temp = stack.pop() + temp;
            }
            stack.pop(); // 弹出 '('
            stack.push(temp);
        } else {
            currentString += char;
        }
    }

    while (stack.length) {
        result = stack.pop() + result;
    }

    return result;
}

// 示例使用
let input = "这是一个(包含(嵌套)括号)的(例子)";
console.log(concatenateNestedBrackets(input)); // 输出: "这是一个包含嵌套括号的例子的"
