0\. We learned a little bit about callbacks in JS. A callback is simply a function passed to another function that gets executed (run) after a potentially long running operation has completed. There is another function called `setTimeout` that will wait a specified period of time and then execute a function. For example:

+
41
+
```js
42
+
functiondoIt() {
43
+
console.log('I am done');
44
+
}
45
+
setTimeout(doIt, 5000)
46
+
```
47
+
48
+
>f you run the above code it will wait 5 seconds and print `I am done`. Please read something about setTimeout on MDN. The first argument to the `setTimeout` call is the callback (`doIt`)

From this line we can define the reducer function as a function that takes an accumulator value and the current array element and returns a new accumulator value.

The whole process is visualised in the figure below (the term _bucket_ was used here to represent the accumulator).

The **reduce()** method is the most flexible of the map/filter/reduce triplet. In fact, it is possible to rewrite **map()** and **filter** using **reduce()**.
