I am working on an assignment for school. I have everything working the way it should be. The only thing that is wrong is how the output is formatted. I am not understanding why I am receiving the output formatted the way it is. I am using javascript, and I am creating nodes and appending them as a child element. My main goal is for each piece of information to be formatted and placed on its own line. this is my javascript function.

function createUserid()

     {
     var firstString = window.prompt ( "Enter first name", "" ); 
             //documentwrite
              var lower = firstString.toLowerCase();
             // firstString.substring(0,4)
             // firstString.concat
     var lastString = window.prompt ( "Enter last name", "" );
     var lowlast = lastString.toLowerCase();
     var socialString = window.prompt ( "Enter social security number without dashes", "" );

     var ln = lowlast.substring(0,4);       //first 4 of last name
     var ls = socialString.substring(5,9);  //last 4 of social
     var fs = socialString.substring(0,5);  //first 5 of social
     var fn = lower.substring(0,4);         //first 4 of first name


             //var user = docoument.write("<p>" + "Username: " + lastString +
             //var pass = <p>"Password: " +

             //var myDiv = document.getElementById('here');
             //myDiv.innerHTML = ____ ;


        var e = document.getElementById('info');
        var o = document.getElementById('here');

        //creating 2 elements: p, br
        var newPara = document.createElement('p');
        var tBR = document.createElement('br');

        //prepare text nodes
        var first = document.createTextNode('First name: ' + firstString);
        var last = document.createTextNode('Last name: ' + lastString);
        var social = document.createTextNode('Social Security #: ' + socialString);
        var userN = document.createTextNode('Username: ' + ln + ls);
        var passW = document.createTextNode('Password: ' + fs + fn);

        //put together paragraph            
        newPara.appendChild(first);
        newPara.appendChild(tBR);
        newPara.appendChild(last);
        newPara.appendChild(tBR);
        newPara.appendChild(social);
        newPara.appendChild(tBR);
        newPara.appendChild(userN);
        newPara.appendChild(tBR);
        newPara.appendChild(passW); 

        //insert into div id of info
        document.getElementById('info').appendChild(newPara);





        o.style.display = 'none';
        e.style.display = 'block';      

    }

this is the output I am receiving

this is how the output is supposed to look.

You are appending same node again and again.

newPara.appendChild(first);
    newPara.appendChild(tBR);
    newPara.appendChild(last);
    newPara.appendChild(tBR);  <--- this node gets moved, since you append it again.
    newPara.appendChild(social);
    newPara.appendChild(tBR);
    newPara.appendChild(userN);
    newPara.appendChild(tBR);  <--- this is where tBR will be at last.
    newPara.appendChild(passW); 

Instead do this :

 var first = document.createTextNode('First name: ' + firstString + '<br/>');

Or this :

        newPara.appendChild(first);
        newPara.appendChild(document.createElement('br'));
        newPara.appendChild(last);
        newPara.appendChild(document.createElement('br'));

Documentation here : https://developer.mozilla/en-US/docs/DOM/Node.appendChild

Adds a node to the end of the list of children of a specified parent node. If the node already exists it is removed from current parent node, then added to new parent node.

If child has already been inserted, element.appendChild(child) removes it from where it was before inserting it at its new location.

Use node.cloneNode(true) to make copies of the child, or just use document.createElement('br') again and again (possibly in a loop to avoid repeating yourself).

Try this:

var first = document.createTextNode('First name: ' + firstString + '<br>');
var last = document.createTextNode('Last name: ' + lastString + '<br>');
var social = document.createTextNode('Social Security #: ' + socialString + '<br>');
var userN = document.createTextNode('Username: ' + ln + ls + '<br>');
var passW = document.createTextNode('Password: ' + fs + fn + '<br>');
