Adding code into return statement in module.php

[galactic]

I want put my html content into return statement in module.php to display on page, hook to 'home' area and 'footer'. Code includes a few divs and a few external and internal javascripts, which have a curly brackets inside. Should I just insert my code inside of quotation marks as is? Or internal javascripts should be included inside a special markup?

 

public function hookHome($params)

{
 return "My html content to display... ...";
}

public function hookfooter($params)

{       
  return $this->hookHome($params);
}
