Title: Fix additional syntax errors on wk-skelton.html

I guess this.super([foo]) is not intended here and there. It creates another Array that contains the original array as the first element, and passes it to the super class. E.g.,

var a = [1,2,3];
foo([a]);

function foo(a) {
console.log(a); // Here, a is [[1,2,3]], and a[0] is [1,2,3].
};
