Thank you, I didn’t realize how powerful map was and plan to use it..a lot. I’m into chatbots and I’m using Botkit by howdy. It’s wonderful but trying to learn node.js lol didn’t know it going in but determined too make the bot do things I need it to do. I’d love to see how to handle json request/response data in node.js. Botkit allows for message attachments and I really feel that asking my bot to fetch me data is/has been the future. The whole asking a chatbot for info over simply looking it up is interesting to me and I think that is powerful.

hi, map itself is not promisable ? it depends on the await function run inside, which in this case is axios which does have a promise wrapper... in your example it makes it seem that any function run inside a map function is promisable.
