What is this? It's not a function?

Not sure what you mean -- I'm just checking here to make sure that the
"startsWith" function doesn't already exist before I install a new one.  Is
there another idiom for doing that?

OK, yeah, so if you are just polyfilling String.startsWith, add a comment to
that effect. You might also want to look at:

+  if (typeof String.prototype.startsWith != 'function') {
+    String.prototype.startsWith = function (str){
+      return this.slice(0, str.length) == str;
+    };
+  }
+
   return sk;
 }();
