这个数字可以通过 Number.MAX_SAFE_INTEGER 常量获取。 基础概念 双精度浮点数:在IEEE 754标准中,双精度浮点数占用64位,其中1位用于符号,11位用于指数,剩下的52位用于尾数(有效数字)。 最大安全整数:指的是在JavaScript中能够被精确表示且没有舍入误差的最大整数。 相关优势 广泛的数值范围:尽管有最大安全整数...

在日常业务开发中,经常会遇到对文件的类型进行校验。文件类型校验可以弱校验,即仅根据文件的后缀名进行类型校验。但是这种校验方式无法识别恶意更改文件后缀名的情况。因此也存在对文件类型进行强校验的方式,即读取文件的十六进制流,根据十六进制编码匹配文件类型魔数(Magic Number)进行判断。

That leaves underscore, which could be the start of an identifier. Currently100_000would be tokenized as "integer literal 100" followed by "identifier _000". However, users would never write an identifier adjacent to another token that contains identifier-valid characters (unlike strings, which ha...
