# Reduce vs Each With Object

Both methods serve the same purpose : from an Enumerator create a single value
out of it

## Reduce

Reduce is prefered when you need to produce a simple value because it reduce over the returned value

```ruby
[1, 2, 3].reduce(:+)
> 3
```

We can illustrate this simply with this snippet :

```ruby
[1, 2, 3].reduce do |acc, v|
  acc += v
  0
end
> 0
```

## Each With Object

Each with object is prefered when you reduce on a hash or some sort of complex
object beacause is use the accumulator value and not the returned one

```ruby
[1, 2, 3].each_with_object({ sum: 0 }) do |v, acc|
  acc[:sum] += v
  0
end
> {sum: 6}
```

**Fun fact**, `reduce` takes `|acc, v|` while `each_with_object` take `|v, acc|`
