Description

/=操作符是让变量与另一个数相除并赋值。 myVar = myVar / 5; 变量myVar等于自身除以5的值。等价于: myVar /= 5;

Instructions

使用/=操作符实现同样的效果。

Tests

tests:
  - text: <code>a</code>应该等于<code>4</code>。
    testString: assert(a === 4);
  - text: <code>b</code>应该等于<code>27</code>。
    testString: assert(b === 27);
  - text: <code>c</code>应该等于<code>3</code>。
    testString: assert(c === 3);
  - text: 应该对每个变量使用<code>/=</code>操作符。
    testString: assert(code.match(/\/=/g).length === 3);
  - text: 不要修改注释上面的代码。
    testString: assert(/var a = 48;/.test(code) && /var b = 108;/.test(code) && /var c = 33;/.test(code));

Challenge Seed

var a = 48;
var b = 108;
var c = 33;

// Only modify code below this line

a = a / 12;
b = b / 4;
c = c / 11;

After Test

(function(a,b,c){ return "a = " + a + ", b = " + b + ", c = " + c; })(a,b,c);

Solution

var a = 48;
var b = 108;
var c = 33;

a /= 12;
b /= 4;
c /= 11;
