*=
操作符是让变量与一个数相乘并赋值。
myVar = myVar * 5;
变量myVar
等于自身与数值5
相乘的值。也可以写作这样的形式:
myVar *= 5;
--instructions--
使用*=
操作符实现同样的效果。
--hints--
a
应该等于25
。
assert(a === 25);
b
应该等于36
。
assert(b === 36);
c
应该等于46
。
assert(c === 46);
应该对每个变量使用*=
操作符。
assert(code.match(/\*=/g).length === 3);
不要修改注释上面的代码。
assert(
/var a = 5;/.test(code) &&
/var b = 12;/.test(code) &&
/var c = 4\.6;/.test(code)
);
--seed--
--after-user-code--
(function(a,b,c){ return "a = " + a + ", b = " + b + ", c = " + c; })(a,b,c);
--seed-contents--
var a = 5;
var b = 12;
var c = 4.6;
// Only change code below this line
a = a * 5;
b = 3 * b;
c = c * 10;
--solutions--
var a = 5;
var b = 12;
var c = 4.6;
a *= 5;
b *= 3;
c *= 10;
