One thing that's really important when you're working with code is to know how it's being
0:03
used, especially if you're going to make changes to it.
0:06
If you're going to add new features or you're considering removing it,
0:09
you think maybe maybe no one's using it?
0:12
Are you sure? So one really neat feature we can do on many symbols,
0:16
on variables, on functions on classes and so on as we can right click and
0:20
say find usages. If we hit that,
0:23
it will actually show us the code all the places in our code where that's being
0:27
used. So for example, here is the definition of get details and down here
0:32
in program share titles in that function or calling this line episode =service.get_details
0:38
and that's where it's being used.
0:40
Obviously in our simple little example here,
0:42
we only have one place where it's being used.
0:45
But in a real app, you probably have many places that you could jump around
0:48
and find where the codes being used.
0:50
So make sure that you use this to understand how the code being used across the entire project.
