Should I learn/become proficient in Javascript?

Question

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

Answer 1

I'll go with the opposite answer most are putting out there. Learning javascript as a developer these days is almost pointless. The language is similar enough to java/C# that it's syntax and semantics shouldn't be lost on you.

What you should learn is jQuery.

As you use jQuery you'll pick up the most common things you'll ever need from javascript anyway.
