There might be situation where you want to display content on all pages exept of the home page. Because of page speed you want to check that before loading the content.
To be able to implement this we need to prepare a variable which we can use to ckeck if we currently are on the Home tab. How to:
isHome will return true when the page that is beiing loaded is the Home tab and will return false on every other Page.
You are finished this variable will be checked early enough in the loading process that it wont influence your page speed. And you can now use it to create conditions in your template.
