<script>
var one = "abc";
var two = "def";
var three = one.concat(two)
var four = three.length;
var variableLen = one.concat(three, four);
document.getElementById("label_one").innerHTML = one;
document.getElementById("label_two").innerHTML = two;
document.getElementById("label_three").innerHTML = variableLen;

Try this [one,two].join(' ');
(Adapt to your needs as necessary, i.e. build an array of strings, then use join)

One way of doing it is:
var one = "abc";
var two = "def";
var three = one.concat(" ", two);
var four = three.length;
var variableLen = one.concat(" ", two, " ", four);
However it might be better to use join as another answer mentions. On a side note, you might notice that the concat() function takes a variable number of arguments. You can achieve this in your own functions like this:
function func1() {
console.log(arguments); // => [1,2,3]
}
func1(1, 2, 3);
