Vba why use set

As part of the huge code, it is frustrating to type the worksheet name like this every time you need to reference the worksheet. The moment we set the worksheet name, we can see the variable name while entering the code as part of the list. When we work with different workbooks, it is so hard to type in the full name of the workbook, along with its file extension. Using this variable, we can actually access all the properties and methods associated with the workbook. This makes the writing of the code lot simpler, and also, once the workbook name is set, there is a worry of typo error of the workbook names.
