I am new to jQuary and although I can write functions I can only seem to write a function for everything! One of the methods people use at work is writing functions as variables to cut down on code. However I just can’t grasp this – I find it confusing. Are there any tutorials for doing this particular method?

Example below

1. $('.PatchyTopPopUpDiv').click (function () {
2. 
   
3. var ToolTipLink = "#";
4. 
   
5. var ToolTipImage = $(this).attr('id');
6. 
   
7. var ToolTipDiv = "Div";
8. 
   
9. var EmailTool = "-Email";
10. 
    
11. var ShowToolTip =ToolTipLink+ToolTipImage+EmailTool
12. 
    
13. $(ShowToolTip).fadeIn ();
14. 
    
15. });
