Having taught javascript to coworkers who were proficient in other languages (c++, c#, ect), javascript was confusing to them since many things act differently in javascript from other languages. That said, with the availability of online help and tutorials, you could definitely get off the ground with it, but it will give you a very different experience than something like python. Depends if you are more interested in programming fundamentals or in web programmings. If you are looking for fundamentals, I would learn Python or Java.
