--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++;
