In this example, it is important to write 'o' before '+', because this metacharacter checks if there is a preceding character present (there must be one of the repeating characters to check!). However, you could avoid this by using the asterisk ('*') metacharacter.

This matches the string perfectly without having to know about the preceding character beforehand.

// Adding a function to wrap the existing code

function findMatch() {

    let s = 'Zoooooootopia';

    if (/Z*topia/.test(s)) {

        console.log("Found a match!");

    } else {

        console.log("Did not find a match.");

    }

}

// Driver code to execute the function

findMatch();
