                [Notes] YDKJS - ASYNC
              
          
    Promises


Goal

Uninvert the inversion of control → instead of handling the continuation of out program to anther party, we could expect it to return us a capability to know when its task finishes, and decide what our code to do next.
What is a Promise


Future Value
