Yeah, that directory on a Mac is "/tmp". So, actually, it IS just as easy on a Mac.
Being new to a Mac means that you are learning, which means you have to help us teach you what you want to learn and what you want to know.
Unlike Windows, Mac is based on Unix which deals with tmp files/folders in a different way. You don't build up cruft over time and need to manually deal with it.
If you are interested in clearing your Browsers cache, you do so from within the Browser itself. If there is another applications temporary history you wish to delete, it'd be good to know what that application is.
Otherwise, there is absolutely no reason for you to manually delete files in the temp folder.
And, oh, punctuations please!
