Ask HN: Good intro to programming course online for those with no experience?

I have a few friends that are looking to get into coding or at least to explore whether or not it might be a good fit for them. So, I was wondering if any HNer happen to know of any good online courses to serve as an intro to programming that would fit that bill. Being taught in a language that may have wider usage I think would be a plus. Having both paid and free/low cost options would be helpful as well for others that happen to read this topic.
