如何在函数中接受字符串类型，然后将其映射到typescript中的键值对？

function mapStringToKeyValue(str: string): { [key: string]: any } {
    // 实现代码
}

function mapStringToKeyValue(str: string): { [key: string]: any } {
    const keyValue: { [key: string]: any } = {};
    // 实现代码
}

function mapStringToKeyValue(str: string): { [key: string]: any } {
    const keyValue: { [key: string]: any } = {};
    const pairs = str.split(';');
    
    for (const pair of pairs) {
        const [key, value] = pair.split('=');
        keyValue[key] = value;
    }
    
    return keyValue;
}

function mapStringToKeyValue(str: string): { [key: string]: any } {
    const keyValue: { [key: string]: any } = {};
    const pairs = str.split(';');
    
    for (const pair of pairs) {
        const [key, value] = pair.split('=');
        keyValue[key] = value;
    }
    
    return keyValue;
}

const input = "name=John;age=25;gender=Male";
const result = mapStringToKeyValue(input);
console.log(result);  // 输出: { name: "John", age: "25", gender: "Male" }
