JS: check if a single character is NOT a whitespace

Question

How to check in JavaScript if the specified character is not a whitespace using regex only? Right now I am doing something like the code below with negation ! but I would like to avoid mixing of two things to avoid confusions.

if (!/\s/.test(character))
    console.log('this is not a whitespace');

`/\S/.test(character)` -> this is not a whitespace. – revo May 04 '18 at 20:40 — revo, May 04 '18 at 20:40

Use the negated set notation in the regex

/[^\s]/

That will match everything that isnt a whitespace.
