# value - ruby hash to array of pairs

## Ruby Hash to array of values (4)

I have this:

```
hash = { "a"=>["a", "b", "c"], "b"=>["b", "c"] }
```

and I want to get to this: `[["a","b","c"],["b","c"]]`

This seems like it should work but it doesn't:

```
hash.each{|key,value| value}
=> {"a"=>["a", "b", "c"], "b"=>["b", "c"]}
```

Any suggestions?

Also, a bit simpler....

```
>> hash = { "a"=>["a", "b", "c"], "b"=>["b", "c"] }
=> {"a"=>["a", "b", "c"], "b"=>["b", "c"]}
>> hash.values
=> [["a", "b", "c"], ["b", "c"]]
```

I would use:

```
hash.map { |key, value| value }
```

There is also this one:

```
hash = { foo: "bar", baz: "qux" }
hash.map(&:last) #=> ["bar", "qux"]
```

Why it works:

The `&`

calls `to_proc`

on the object, and passes it as a block to the method.

```
something {|i| i.foo }
something(&:foo)
```

```
hash = { :a => ["a", "b", "c"], :b => ["b", "c"] }
hash.values #=> [["a","b","c"],["b","c"]]
```
