# Create A Hash From An Array Of Arrays
|
|
|
|
The `::[]` method on the `Hash` class allows you to succinctly create a hash
|
|
from an array of arrays -- or rather an array of tuples which are key value
|
|
pairs.
|
|
|
|
```ruby
|
|
> Hash[ [["a",2],["b",4]] ]
|
|
{"a"=>2, "b"=>4}
|
|
> Hash[ [[1,2],[3,4]] ]
|
|
{1=>2, 3=>4}
|
|
```
|
|
|
|
See the [`Hash::[]`
|
|
docs](http://ruby-doc.org/core-2.3.0/Hash.html#method-c-5B-5D) for more
|
|
details.
