Javascript triangle project

So I'm trying to write a JS that takes the sides of triangles and determines if they're real or not. It keeps fucking up though and I have NO idea why.
Code:
//Gather input
var side1 = prompt("Input the length of side A(Not the longest).");
var side2 = prompt("Input the length of side B(Not the longest).");
var side3 = prompt("Input the length of side C(Longest side).");
//Create triangle object
var triangle = new Object();
//Find out if the triangle is real
real = function() {
if (side1 + side2 <= side3 || side2 + side1 <= side3) {
triangle.real = "not real";
}
else{
triangle.real = "real";
}
};
//Call functions and display answer
real();
alert("The triangle is " + triangle.real + ".");

if you're a javascript guy, you are the javascript guy.

i don't know what kind of retarded shit have you smoked lately, but there's no way someone would troll the shit out of /prog/ for an indefinite time with a really bad language

Ahmed is doing the same thing, except ``Symta'' is better than javascript
