Why might a programmer decide to use a third-party package ?

as part of their program/application?
gpt
Pick one or more:

* Can't be bothered to write their own
* Straight-up **can't** write their own
* Don't have the time to write their own
* Found really nice documentation that makes their problem easier
* Used the library previously and don't want to re-learn a new one

Third-party packages / libraries range everything from "pad this string to a certain size" to "do 3D electromagnetic simulation at 60GHz".  It's hard to talk about the whole thing as one set without being extremely vague.
