Newbie Queary - Can someone understand Javascript too well?
<p><strong>A bit of a back-story on this/Why I'm still a "noob"</strong><br/>
A little over a month ago I started my venture in to full-on web development. So far I've learned the basics and have a fair understanding of CSS/CSS3, XHTML and how to use them to make a functional, practical website without too much of an issue. Last week I began my first few Javascript tutorials and I'm finding it to be a rather amazing language. After viewing some of the entries for the <a href="http://js1k.com/" rel="nofollow">JS1k</a> challenge and other various practical implications on existing websites, it seems that it's bounds are only limited to the programmer's abilities. I don't know enough of what this language can do as I'm still memorizing it's syntax, but I'm quite amazed with what I've seen so far. </p>

<p>All this being, a few important questions have come to mind and I've been unable to find anything that can answer them. I'm burnt out on searching and I was hoping you all would be able to help me out.</p>

<h2>At what point can I say to someone "I know Javascript"?</h2>

<p>I know that I'll eventually be able to do most anything with this language, but what do I NEED to know to make use of it in today's world? I understand I'd be expected to have a full grasp of syntax, as with any language, but what is to be expected of someone as far as specifics go? What will an employer expect me to be able to do without having to look at a reference?</p>

<h2>Is it possible to know JS so well people will laugh, or is this a case of "the more the better"?</h2>

<p>While I'm aware you can render 3d images and make basic games with Javascript, I'm unsure if something like that makes me a better qualified programmer or if it's just overkill. As a person looking to sell their craft, how much is too much?</p>

<p>Any help with answering these is immensely appreciated. Thanks in advance :)</p>
