I think it's the case with everything. I've seen piano players on YouTube just pick up a ukelele in a few hours. I managed to pick up and even interview with Swift with little effort but I've never used it in a real capacity. JS and C were different though. Someone good in C would have trouble with JS compared to someone who has no experience in either. But learn both, and you'll be good.
