FileTypes

File-Types

JSON:

JSON is quite a common file type for configuration/storage files, it is rather fast but fairly hard to read as a human.

YAML

YAML is not as fast as JSON but way easier to read, which is why Most Minecraft plugins rely on it as their configuration file (mostly config.yml).

TOML

TOML is a compromise between the readability of Yaml and the performance of JSON, thus being a quite good way to go.
