Very nice! I remember when I started to learn C two months ago, I got started with printing hello world but things got very complex later on but one thing I am grateful for is that I didn't give up.
Goodluck with your learning, it will tremendously supplement your knowledge of JavaScript and it will make you a better programmer when you eventually become a master at C
This is the main reason why I am learning C. Felt it is important to learn it.
