#鸿蒙通关秘籍#鸿蒙开发中的multiton启动模式有什么特点？

class Multiton {
    static instances = {};

    constructor(key) {
        if (!Multiton.instances[key]) {
            Multiton.instances[key] = this;
        }
        return Multiton.instances[key];
    }
}

// 使用示例
const instanceA = new Multiton('A');
const instanceB = new Multiton('B');
const anotherInstanceA = new Multiton('A');

console.log(instanceA === anotherInstanceA); // 输出: true
console.log(instanceA === instanceB); // 输出: false
