20 Dec, 2023
The RegExp \s Metacharacter in JavaScript is used to find the 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 replaces the white spaces with a dash.
Javascript
function geek() {
let regex = /\s/g;
let replace = "-";
let str = "GeeksforGeeks is the computer "
+ "science\nportal\tfor geeks.";
let str1 = str.replace(regex, replace);
console.log("The new string is: \n" + str1);
}
geek()
|
Output
The new string is:
GeeksforGeeks-is-the-computer-science-portal-for-geeks.
Example 2: This example replaces all the white spaces with hash(#).
Javascript
function geek() {
let regex = new RegExp("\\s", "g");
let replace = "#";
let str = "Geeks Classes is a Classroom "
+ "programme\nby GeeksforGeeks\tto"
+ " enhance DSA";
let str1 = str.replace(regex, replace);
console.log("The new string is: \n" + str1);
}
