We need to get its permalink value to get the list of comments. We can write a separate method for getting a list of comments for the given URL. We call this method getComments. The implementation of getComments is simple

getComments.js

let getComments = (link) => {
    let response
    try {
        response = JSON.parse(request('GET',"https://www.
        reddit.com/" + link).getBody('utf8'))
    } catch(err) {
        response = { message: "Something went wrong" ,
        errorCode: err['statusCode'] }
}
    return response
}
