The RegExp m* Quantifier in JavaScript is used to find the match of any string that contains zero or more occurrences of match.
let str = "GeeksforGeeks@_123_G$";
let regex = /ke*/gi;
let match = str.match(regex);
console.log("Found " + match.length
+ " matches: " + match);
Output
Found 2 matches: k,k
Syntax:
/m*/
Example 1: Matches the zero or more occurrences of the word 'e' in the whole string.
let str = "GeeksforGeeks@_123_G$";
let regex = /Ge*/gi;
let match = str.match(regex);
console.log("Found " + match.length
+ " matches: " + match);
Output
Found 3 matches: Gee,Gee,G
Example 2: Replaces the occurrence of 128* with the word "Geeky".
let str = "GEEK@128";
let regex = new RegExp("128*", "gi");
let replace = "Geeky";
console.log(str.replace(regex, replace));
Output
GEEK@Geeky
