JavaScript RegExp g Modifier
Last Updated :
30 May, 2023
The RegExp g Modifier in JavaScript is used to find all the occurrences of the pattern instead of stopping after the first match i.e it performs a global match.
Syntax:
/regexp/g
or
new RegExp("regexp", "g")
Example 1: This example searches the word “geeks” in the whole string.
Javascript
function geek() {
let str1 = "geeksforgeeks is the computer "
+ "science portal for geeks." ;
let regex4 = /geeks/g;
let match4 = str1.match(regex4);
console.log( "Found " + match4.length
+ " matches: " + match4);
}
geek()
|
Output
Found 3 matches: geeks,geeks,geeks
Example 2: This example searches the word “portal” in the whole string and replaces it with “PORTAL”.
Javascript
function geek() {
let str1 = "geeksforgeeks is the computer "
+ "science portal for geeks." ;
let regex4 = new RegExp( "portal" , "g" );
let replace = "PORTAL" ;
let match4 = str1.replace(regex4, replace);
console.log( " New string: " + match4);
}
geek()
|
Output
New string: geeksforgeeks is the computer science PORTAL for geeks.
