Language of programming

Can u tell me which language is used for programming bolt?

Javascript, I guess. Technically, you don’t program the bolt. It’s already done for you.

What you do is create an HTML page with the relevant CSS and Javascript and use in built functions to manipulate the bolt’s I/O pins. That’s about it. Pretty small, but mix it with you’re creativity and you’ll soon be solving problems with the bolt in no time.
