JSON and TOML (Tom's Obvious, Minimal Language) are both commonly used for configuration files.
JSON is a widely used data interchange format that is easy to read and write for humans and machines alike. It uses a simple syntax that is easy to understand and is supported by most programming languages. JSON is also a subset of JavaScript, so it can be used directly in JavaScript without any additional parsing or conversion.
TOML, on the other hand, is a minimal configuration file format that is designed to be easy for humans to read and write. TOML uses a simple syntax that is similar to INI files, with key-value pairs separated by an equals sign. TOML also has a stricter syntax than JSON and YAML, which can make it easier to parse and less prone to errors.
Both JSON and TOML have their own advantages and disadvantages. JSON is widely supported and can be easily used with most programming languages, while TOML has a simpler syntax and is less prone to errors. So depending on your use case, you can choose one over the other.
In summary, JSON is widely supported and easy to use in many programming languages, while TOML has a simpler syntax and is less prone to errors.
