This code inside else and the if is pretty much same except for the for loop. can you think of a way to reuse the code?

Yes, if we push the single element to array and then for each element, call the requestTitle().But it will come with the cost of time complexity as even for a single element in array , it will go into for loop. I have chosen this solution , "if" concludes if the given parameters are in array , then for each element(param) in array call the function requestTitle() where as for a single param, just call requestTitle() not to trade time complexity.

const values= Array.isArray(request.query.address) ? request.query.address: [request.query.address] || [ ];
    var arrayLength = values.length;
    for (var counter = 0; counter < arrayLength; counter++) {
    helper.requestTitle(values[counter], (title) => {   
        responseHelper.sendDescription(response, title);

    });}
