# 137Decrement a Number with JavaScript（变量增1）

最近更新时间：2017年7月28日13:08:03

说明：

```
使用 ++ ，我们可以很容易地对变量进行自增或者+1运算。

i++;

等效于

i = i + 1;

提示
i++;这种写法，省去了书写=符号的必要。

任务
重写代码，使用 ++ 来对变量 myVar 进行自增操作。


myVar 应该等于 88
使用 ++ 运算符
不要修改注释上方的代码
```

原始代码：

```
var myVar = 87;

// 请只修改这条注释以下的代码
myVar = myVar + 1;
```

调试代码：

```
var myVar = 87;

// 请只修改这条注释以下的代码
myVar++;
```
