Javascript examples tend to zombify quite fastly. It’s pretty easy to make up a page for showing something, but very soon that page becomes unusable. I’m constantly finding many broken javascript examples in the internet.
And the semantic of a broken javascript example is a logic problem nobody can solve. Is it broken by accident or on purpose? Was it already broken when created? Who, what, where, when did it break? Is it a browser test? Am I doing something wrong?
Maybe we should refrain from presenting online examples.
