diff between helper and plugin

[eluser]Unknown[/eluser]
Please, can anyone Tell me the difference between helpers and plugins?

A helper is a collection of related functions and a plugin is one function.

Plugins are mend for just one function, where as helpers contain a couple of functions. That's the only difference I know.

Library — include, instanciate, attach to Controller.

Plugin is identical to Helper but commonly include different things:

Plugin — include. Mostly for external classes / functions.
Helper — include. Mostly for view functions.

The difference between Plugin and Helpers is not where it is used... The User guide defines it

Plugins work almost identically to Helpers. The main difference is that a plugin usually provides a single function, whereas a Helper is usually a collection of functions. Helpers are also considered a part of the core system; plugins are intended to be created and shared by our community.
