7 | When given a hash this function will return the values of that hash.

9 | *Examples:*
|
---|
10 |
|
---|
11 | $hash = {
|
---|
12 | 'a' => 1,
|
---|
13 | 'b' => 2,
|
---|
14 | 'c' => 3,
|
---|
15 | }
|
---|
16 | values($hash)
|
---|
17 |
|
---|
18 | This example would return:
|
---|
19 |
|
---|
20 | [1,2,3]
|

21 | EOS
