What is a Promise?

Question

Currently, learning the last course of javascript(the promise lesson) and ended up confusing. I felt something is missing so I searched through google and found out about synchronous and asynchronous. What are they? What the correlations between them and promise? Are they really not important to learn so sololearn skip them? But my main question, what a promise is exactly?

ps: I have read a few articles but am not really sure myself, so I want to hear the thoughts of people here

Promise is ES6;

In ES7, there is async await which is much much easier.

Here is an awesome async await tutorials shared by David Carroll :
