Question

Artificial intelligence

I want to write an interlocutor program, but I don’t know how to design and what technologies to use? From languages ​​I know only JS. What to use as a core, so that in the future it would be possible to scale (train). And how to connect the program with my own accounts in social networks, so that I myself could communicate with my friends / subscribers and, if possible, learn. Advise, maybe someone knows which side to approach, materials, books, lessons?
