I have removed the following code from the PHP file and it still works. Could you tell me what the purpose of this code is and what it does?

// ################### PRE-CACHE TEMPLATES AND DATA ###################### 
// get special phrase groups 
$phrasegroups = array( 

); 

// get special data templates from the datastore 
$specialtemplates = array( 
     
); 

// pre-cache templates used by all actions 
$globaltemplates = array( 
    'TEST', 
); 

// pre-cache templates used by specific actions 
$actiontemplates = array( 

);
