Reducer

Okay kiddo, let me try to explain what is a reducer in a way that you can understand. Imagine that your toy box is full of different kinds of toys. You have cars, dolls, balls, and blocks. Now, suppose you want to count how many cars you have in your toy box, you could do it by hand, but it would take a long time.

This is where a reducer comes in handy. A reducer is like a helper that helps you count things very quickly. It's like a big magic sorting hat that can sort your toys without you having to do it all by yourself.

In programming, reducers are used to take a lot of data or information and then boil it down to just one result. Think of it like a recipe for a cake. Imagine that you have all the ingredients for a cake, like sugar, butter, eggs, and flour. A reducer will take all of these ingredients and mix them together to create a delicious cake.

Similarly, in programming, reducers take lots of data or information and mix it all up to create one answer. For example, if you have a list of numbers and you want to add them up, a reducer could help you by adding all the numbers together and then giving you the total.

So, there you have it, a reducer is like a magic helper that helps you sort and count things very quickly, just like how you can sort your toys in your toy box to find your cars easily or mix all the ingredients of your favorite cake recipe to make a delicious cake.
