Welcome to the forum.
According to Wikipedia:
"where we can use it" most functions
"where we cannot use it" the article doesn't really say
"why we use it" to make tricky diffs a bit easier.
But why would you do this for an example that can be done more easily. In practice, you would use it only when it makes things easier, such as this second example:
