JavaScript评估
可以将JavaScript表达式计算为.less文件内的值。我们建议谨慎使用此功能，因为LESS不能由端口编译，这使得LESS难以维护。如果可能，尝试想一个可以添加以实现相同的目的，并要求在github上的函数。我们计划允许扩展可用的默认功能。但是，如果您仍然想要在.less中使用JavaScript，则可以通过将表达式换行为反转的方式来实现：

JavaScript evaluation JavaScript expressions can be evaluated as values inside .less files. We recommend using caution with this feature as the LESS will not be compilable by ports and it makes the LESS harder to maintain. If possible, try to think of a function that can be added to achieve the same purpose and ask for it on github. We have plans to allow expanding the default functions available. However, if you still want to use JavaScript in .less, this is done by wrapping the expression with back-ticks:

应该工作：

@var: `Math.random()`;
