how to search for everything else but whitespace using regular expression in JavaScript

Comment

/* This pattern will not match whitespace, 
carriage return, tab, form feed, and new line characters. 
You can think of it being similar to the character class [^ \r\t\f\n\v]*/
let sample = "Whitespace is important in separating words";
let countNonWhiteSpace = /\S/g; // Change this line
let result = sample.match(countNonWhiteSpace);
