--description--
我们也可以在 JavaScript 中进行减法运算。
JavaScript 中使用-来做减法运算。
示例
myVar = 12 - 6; // assigned 6
--instructions--
改变数字0让变量 difference 的值为12。
--hints--
要使difference的值等于 12。
assert(difference === 12);
只用 45 减去一个数。
assert(/var\s*difference\s*=\s*45\s*-\s*[0-9]*;(?!\s*[a-zA-Z0-9]+)/.test(code));
--seed--
--after-user-code--
(function(z){return 'difference = '+z;})(difference);
--seed-contents--
var difference = 45 - 0;
--solutions--
var difference = 45 - 33;
