Should I learn/become proficient in Javascript?
<p>I am a .NET webdev using ASP.NET, C# etc... I "learned" javascript in college 5+ years ago and can do basic jobs with it. But I wonder if it is useful to become proficient in it.</p>

<p>Why should I learn Javascript?
Is it more advantageous then learning JQuery or a different <a href="http://stackoverflow.com/questions/913/what-javascript-library-would-you-choose-for-a-new-project-and-why">library</a>?</p>
