A docstring is a comment written on the first statement of a module, function, class, or method definition.
For example in python it would be something like this:
"""Esta documentación es más larga: Contiene más líneas de información """In JavaScript something like:
/** * [bar description] * @param {[type]} foo [description] * @return {[type]} [description] */
