This is a simple repo containing functions that calculate the nth Fibonacci number in several different languages to demonstrate syntax differences and approximations of running times. I'm by no means fluent in these languages, so it's very possible and highly probable that my code will be sub-optimal in some cases.
Note: Values of 0 indicate inability to accurately time.

Iterative (100th fib number calculated 10 times in case integer overflow makes calculations simpler (I don't know, and if this is contributing even more error, please let me know!))
