I swear I see this topic across various forums on a daily basis.

But anyway in no specific order:

Python - The simplicity of the language was an invaluable gateway into programming for me. I worried much less about syntax than I did when I learned Java in HS, and spent much more time focusing on actual concepts of programming as a whole. It's still my go-to language when applicable.

Javascript - I continuously get blown away by the things people are able to do with this language across the web. Recent example: Bellard's Linux emu.

C - After I had a firm grip with python I began picking this up via the K&R bible, and I still find myself challenged by either concepts or the use of the language itself when using it.
