 TODO: some more shit

+## Examples
+
+Below is our standardized [divisor tree](divisor_tree.md) program written in browser JavaScript:
+
+```
+<html> <head> <script>
+
+// recursive function, returns divisor tree of x as a string
+function divisorTreeStr(x)
+{
+  let a = -1, b = -1;
+  let s = "";
+
+  for (let i = 2; i <= x / 2; i++) // find closest divisors
+    if (x % i == 0)
+    {
+      a = i;
+      b = x / i;
+
+      if (b <= a)
+        break;
+    }  
+
+  s += "("
+
+  s += a > 1 ?
+    divisorTreeStr(a) + " " + x + " " + divisorTreeStr(b) : x;
+
+  return s + ")";
+}
+
+function main()
+{
+  while (true) // main loop, read numbers from the user
+  {
+    let x = parseInt(prompt("enter a number:"));
+
+    if (isNaN(x) || x < 0 || x >= 1000)
+      break;
+
+    console.log(divisorTreeStr(x));
+  }
+}
+
+</script> </head> <body onload="main()"> </body> </html>
+```

 ## JavaScript Fun

 Here let be recorded funny code in this glorious language.
