As we saw with promises after it resolves we need to call .then() and it is not really sequential as we would like it. that’s what async await is all about. async await is a new way to write asynchronous code and was basically created for simplifying how we can write chained promises. async await is nonblocking like we would expect it to be. These concepts include callback functions, promises and the use of async, and await to handle different operations in javascript. before jumping to comparison between the three, let's get a brief understanding of synchronous (blocking) and asynchronous(non blocking).
