JavaScript RegExp + Quantifier

The m+ Quantifier in JavaScript is used to find the match of any string that contains at least one m. 

Syntax: 

/m+/ 

or

new RegExp("m+")

Syntax with modifiers:

/\m+/g 

or

new RegExp("m+", "g")

Example 1: This example matches the presence of the word ‘e’ in the whole string. 

Javascript

function geek() {
    let str1 = "GeeksforGeeks@_123_$";
    let regex4 = /e+/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 ‘EE’. 

Javascript

function geek() {
    let str1 = "GeeKY@128";
    let regex4 = new RegExp("e+", "gi");
    let replace = "EE";
    let match4 = str1.replace(regex4, replace);
    console.log(" New string: " + match4);
}
geek();

Output

 New string: GEEKY@128
