Hash Tables are a great way to organize data. A hash table stores key-value-pairs. To create a new hash table variable, try this:
$person = @{}
You can then add new key-value-pairs by simply using the dot notation:
$person.Age = 23
$person.Name = 'Tobias'
$person.Status = 'Online'
$person.Name
$person
Optionally, you can use a Hash Table like a field and access its keys in square brackets:
$person['Age']
You can even use other variables to access its keys:
$info = 'Age'
$person.$info
