\s matches whitespace (spaces, tabs and new lines). \S is negated \s.

\s匹配空格(空格、制表符和新行)。\ S是否定\ S。

#2

\S matches anything but a whitespace, according to this reference.

根据这个引用，\S匹配除了空格之外的任何东西。

#3

I believe it means 'anything but a whitespace character'.

我相信它的意思是“除了空白字符之外的任何东西”。

#4

/\S/.test(string) returns true if and only if there's a non-space character in string. Tab and newline count as spaces.

/\S/.test(string)当且仅当字符串中有非空格字符时返回true。制表符和换行符计数为空格。

#5

The \s metacharacter is used to find a whitespace character.

\s元字符用于查找空格字符。
