Can anyone explain how store action creator and reducer works its little difficult to understand

Answer 1

Basically, Reduce method performs a reduction function (provided by you), going through the entire array, and returning its respective object, item or array.

Basic structure:
const finalObject = items.reduce((finalObject, item) => {
/ * Logic for return * /
finalObject.adderItens + = item.subItem
return finalObject
}, {adderItens: 0})

Note: subItem is an element pre-existing items.

For better understand content, I recommend the Digital Innovation One course:
