can't read Element.prototype in firefox

Question

If I run this javascript:

var a,b=Element.prototype;
for(a in b)b[a];

Firefox gives me this error:

TypeError: Value does no         


        

Answer 1

You might want to try using Object.getOwnPropertyDescriptor() in your loop instead of accessing each property directly using the key on the prototype: http://codepen.io/seraphzz/pen/aJgcr
