Is there a difference between space and \s?

Is there a difference between using space and \s in the sets and outside? In the name we use [-\w ] and in job we use [-\w\s]. Can we use just space when specifying the space between the words or only \s?

:point_right: A space just matches a space. The \s code matches any kind of "white space", including space, tab, vertical tab, return, new line, and form feed.

Thanks! What about 2 x space? Is it matched by \s? In this case, it is probably safer to always use \s. Unless you are 100% sure there will be strictly one space.

Daniel Petrov, yes, \s should match almost any kind of whitespace, even letterspaces, tabs, halftabs, newlines etc. Negation 6:00 And, i guess, if you add + it will match 1x and 2x space and more: \s+
