Yes, all the above I guess.
JS is good for hackatons and apps on hyperledger though.
Can we have core blockchain built with Js,i'm afraid not just apps.
sorry if i am interpreting your ans wrong
I'm sure you can find some experiments, but I would not build one in an interpreted language for all the above reasons.
Technically it can be done in any language.
Have you heard of bcoin? It’s bitcoin node software written in JS
perfect match 🎉🎆
I wouldn't recommend it for a "real world" blockchain but it's great for learning purposes. You might enjoy my talk from DevConf Poland this year where I talked about exactly this topic: youtube.com/watch?v=mOjXlb7KZFk
