Adding onto this, overly focusing on a technology can really hamper you while getting jobs later. I want to see that you understand the technology that underpins what you will be doing everyday, not the specific libraries that we'll probably abandon in 2 years anyway. Knowing Angular is a lot less important to me than being an expert in the actual javascript language underneath it. Similarly, it's even more impressive to have a thorough understanding of what's under the hood of javascript, knowing WHY it has it's limitations, instead of just what they are. Depth of a single, particular subject will never beat depth of an entire stack (before hitting the point of ridiculousness, of course).
