Optional
s are a feature widely used in SpongeAPI. This section tries to explain why we need them and how
they’re used. If you already know why we use Optional
s, just head directly to the Kullanım örnekleri section. If you’re
unsure what they are, what they do and why we need them, then Belirtilen özellikler should be the first chapter to read.
