29 May, 2023
The RegExp m{X} Quantifier in JavaScript is used to find the match of any string that contains a sequence of m, X times where X is a number.
Syntax:
/m{X}/
or
new RegExp("m{X}")
Syntax with modifiers:
/\m{X}/g
or
new RegExp("m{X}", "g")
Example 1: This example matches the presence of the word ‘ee’ in the whole string.
Javascript
function geek() {
let str1 = "GeeksforGeeks@_123_$" ;
let regex4 = /e{2}/gi;
let match4 = str1.match(regex4);
console.log( "Found " + match4.length
+ " matches: " + match4);
}
geek();
|
Output
Found 2 matches: ee,ee
Example 2: This example replaces the word ‘ee’ with the character ‘E’.
Javascript
function geek() {
let str1 = "ee@128GeeeeK" ;
let regex4 = new RegExp( "e{2}" , "gi" );
let replace = "E" ;
let match4 = str1.replace(regex4, replace);
console.log( " New string: " + match4);
}
geek();
|
Output
New string: E@128GEEK
