How can I remove the last comma in my for loop?

Question

    if (katzDeliLine.length > 0) {
        var textToPrint = \"The line is currently: \"

        for (var crrLine = 0; crrLine &         


        

Answer 1

You could map the leading numbers with the value and join the array with comma.

function currentLine(array) {
    return array.length
        ? `The line is currently: ${array.map((v, i) => `${i + 1}. ${v}`).join(', ')}.`
        : "The line is empty.";
}

var lineofpeople = ["katrina", "kevin", "vincent"];

console.log(currentLine(lineofpeople));
console.log(currentLine([]));
