Difference between . and #

In Ruby what is the difference between those two (in code):

- `Class.method`
- `Class#method`

The hash format (Class#method) is not valid ruby, but is used in documentation to describe an instance method.

Class methods are typically documented using a double-colon (Class::method).

You will see examples of both in the ruby docs (e.g.

The dot format is used in code when actually *calling* a class method (Class.method), though I have seen some people (unfortunately) use it interchangeably with either the double-colon or hash in documentation.

`Class#method` is not valid code. It is only used in documentation. method should be an instance method.

`Class.method` or object.method is the actual method belonging to the object. Class is an object too. It is valid code.

It's a naming convention.

- use pound `#method` for instance methods
- use dot `.method` for class methods
