# Wrap Things In An Array, Even Hashes
|
|
|
|
I've always used `Kernel::Array` to wrap things in an array. It works great.
|
|
|
|
```ruby
|
|
> Array(nil)
|
|
#=> []
|
|
> Array(1)
|
|
#=> [1]
|
|
> Array(["hello", "world"])
|
|
#=> ["hello", "world"]
|
|
```
|
|
|
|
Except with hashes, it might not do what you expect when given a hash.
|
|
|
|
```ruby
|
|
> Array({a: 1, b: 2})
|
|
#=> [[:a, 1], [:b, 2]]
|
|
```
|
|
|
|
I just wanted the hash wrapped in an array, not turned into an array of tuples.
|
|
|
|
The `Array` class has a method `#wrap` which behaves similarly to
|
|
`Kernal::Array` while also handling hashes in the way I was wanting.
|
|
|
|
```ruby
|
|
> Array.wrap(nil)
|
|
#=> []
|
|
> Array.wrap(1)
|
|
#=> [1]
|
|
> Array.wrap(["hello", "world"])
|
|
#=> ["hello", "world"]
|
|
> Array.wrap({a: 1, b: 2})
|
|
#=> [{a: 1, b: 2}]
|
|
```
