The method isn't suitable for all tasks, but I think that many people work with very big tables in Excel (e.g. You get the speed increase, because there is a large overhead writing to and from a range in a spreadsheet, whereas it is very fast to operate on a virtual table (the array). Once you have finished operating on the array, you copy the array to the spreadsheet in one lightning fast operation. If you work with big tables/ranges, you can usually speed up the code a lot, if you copy the range to an array. You can also download a spreadsheet with the examples.
You can use other criteria, and the task doesn't have to be the removal of rows - that is just the objective for my examples.

It is both easier and faster with an array. You CAN loop through a range and remove or insert e.g. This could be deleting rows in a range (table) or other operations.
