The RegExp \S Metacharacter in JavaScript is used to find the non-whitespace characters. The whitespace character can be a space/tab/new line/vertical character. It is the same as [^\t\n\r].

Syntax:

/\S/ 

or

new RegExp("\\S")

Syntax with modifiers:

/\S/g 

or

new RegExp("\\S", "g")

Example 1: This example matches the non-whitespace characters. 

Javascript




function geek() {
    let str1 = "GeeksforGeeks @ _123_ $";
    let regex4 = /\S/g;
    let match4 = str1.match(regex4);
 
    console.log("Found " + match4.length
        + " matches: " + match4)
 
}
geek();


Output

Found 20 matches: G,e,e,k,s,f,o,r,G,e,e,k,s,@,_,1,2,3,_,$
