`underscore` is a `Go` library providing useful functional programming helpers without extending any built-in objects.
It is mostly a port from the `underscore.js` library based on generics brought by `go1.18`.

Calling `chain.Of` will cause all future method calls to return wrapped values. When you've finished the computation,
call `Value` to retrieve the final value.
Methods not returning a slice such as `Reduce`, `Every`, `Some`, will break the `Chain` and return `Value` instantly.
