An empty hashtable is created in the same manner as the following:

$hashtable = @{} 

A hashtable with a few objects appears as follows:

$hashtable = @{Key1 = "Value1"; Key2 = "Value2"} 

Elements in a hashtable may be spread across multiple lines:

$hashtable = @{ 
    Key1 = "Value1" 
    Key2 = "Value2" 
}
