Ask HN: How do I set up my own simple website on a domain I buy?

This is pretty noobish - but what is everyone's recommendation for setting up a new website? Mainly this will be a personal blog of sorts... so do I buy a domain, then get another service like Heroku to put(publish) my application there?

Any good current tutorials? I'm thinking of working with the MEAN Stack or just in general javascript tech stacks.
