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 don't think a lot of deliberate learning makes sense (but of course you need some basic knowledge), but I also think after some years of web development you'll become pretty proficient in the language anyway :)
