js字符串反转正则

function reverseStringUsingRegex(str) {
    // 使用正则表达式将字符串拆分成字符数组
    let charArray = str.split(/(?<!^)(?<!\b)/); // 使用正则表达式避免拆分出空字符串
    // 反转数组
    let reversedArray = charArray.reverse();
    // 将数组拼接成字符串
    let reversedStr = reversedArray.join('');
    return reversedStr;
}

// 测试
let originalString = "Hello, World!";
let reversedString = reverseStringUsingRegex(originalString);
console.log(reversedString); // 输出: "!dlroW ,olleH"

function reverseString(str) {
    return str.split('').reverse().join('');
}

// 测试
let originalString = "Hello, World!";
let reversedString = reverseString(originalString);
console.log(reversedString); // 输出: "!dlroW ,olleH"
