# Turn Key And Value Arrays Into A Hash
|
|
|
|
Let's say you have an array of keys and an array of values:
|
|
|
|
```ruby
|
|
keys = [:title, :author, :year]
|
|
values = ["The Fifth Season", "N. K. Jemisin", 2015]
|
|
```
|
|
|
|
You can turn them into a hash where the keys of that hash come from `keys` and
|
|
are tied in order, one-to-one with the `values`.
|
|
|
|
A `hash` can be created from an array of tuples, where each is a key-value
|
|
pairing. Knowing this, we can `zip` the two arrays together and then turn them
|
|
into a `hash` like so:
|
|
|
|
```ruby
|
|
> Hash[keys.zip(values)]
|
|
#=> {:title=>"The Fifth Season", :author=>"N. K. Jemisin", :year=>2015}
|
|
```
