调用计数器（支持重置）

[Sunny-117]

class Count {
}
const instance = new Count()
console.log(instance.add())//1
console.log(instance.add())//2
console.log(instance.add())//3
console.log(instance.reset())//1
console.log(instance.add())//1

class Count {
    constructor(value = 0){
        this.value = value;
    }
    add(){
        this.value++;
        return this.value;
    }
    reset(){
        this.value = 1;
        return this.value;
    }
}
const instance = new Count()
console.log(instance.add())//1
console.log(instance.add())//2
console.log(instance.add())//3
console.log(instance.reset())//1
console.log(instance.add())//2

最后一个应该是2吧

class Count {
    constructor() {
        this.count = 0;
    }

    add() {
        return ++this.count;
    }

    reset() {
        this.count = 0;
        return this.add();
    }
}

const instance = new Count();
console.log(instance.add()); // 输出 1
console.log(instance.add()); // 输出 2
console.log(instance.add()); // 输出 3
console.log(instance.reset()); // 输出 1
console.log(instance.add()); // 输出 2
