NaN(Not a Number)通常在计算失败的时候会得到该值。要判断一个变量是否为 NaN,则可以通过 Number.isNaN 函数进行判断。 Infinity 是无穷大,加上负号 “-” 会变成无穷小,在某些场景下比较有用,比如通过数值来表示权重或者优先级,Infinity 可以表示最高优先级或最大权重。 进制转换 当我们需要将其他进制的整数转...

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene have been recognized as genetic risk factors for Parkinson’s disease (PD). However, compared to cancer, fewer genetic mutations contribute to the cause of PD, propelling the search for protein b
