React setState not updating state

Question

So I have this:

let total = newDealersDeckTotal.reduce(function(a, b) {
  return a + b;
},
0);

console.log(total, \'t         


        

Answer 1

The setstate is asynchronous in react, so to see the updated state in console use the callback as shown below (Callback function will execute after the setstate update)

The below method is "not recommended" but for understanding, if you mutate state directly you can see the updated state in the next line. I repeat this is "not recommended"
