--description--

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;

注意
i++;这种写法,省去了书写=符号的必要。

--instructions--

重写代码,使用++来对变量myVar进行自增操作。

提示
了解更多关于++运算符Arithmetic operators - Increment (++).

--hints--

myVar应该等于88

assert(myVar === 88);

myVar = myVar + 1;语句应该被修改。

assert(/var\s*myVar\s*=\s*87;\s*\/*.*\s*myVar\+\+;/.test(code));

使用++运算符。

assert(/[+]{2}\s*myVar|myVar\s*[+]{2}/.test(code));

不要修改注释上方的代码。

assert(/var myVar = 87;/.test(code));

--seed--

--after-user-code--

(function(z){return 'myVar = ' + z;})(myVar);

--seed-contents--

var myVar = 87;

// Only change code below this line
myVar = myVar + 1;

--solutions--

var myVar = 87;
myVar++;
