But overall, the goal should be to get a broad range of experience in different platforms so the technology you use is irrelevant. From that point on you just need to decide where you want to invest your time.
For example, when I was doing internships in college I invested in getting Java experience because I knew that it was used by large companies (companies who pay more). This paid off and I was hired by a company who paid me a lot of money to use Java straight out of college. Now I'm paid a lot of money by another company to use Java.
So you want to have the capability to code in anything, but you have to decide which technologies to put on your resume based on what's out there. Knowing Java, JS, and Web Application Development is never a bad idea.
