Requires that all @param tags have names.
The
@paramtag requires you to specify the name of the parameter you are documenting. You can also include the parameter's type, enclosed in curly brackets, and a description of the parameter.
Set this to an array of strings representing the AST context (or an object with
context and comment properties) where you wish the rule to be applied.
Overrides the default contexts (see below). Set to "any" if you want
the rule to apply to any jsdoc block throughout your files (as is necessary
for finding function blocks not attached to a function declaration or
expression, i.e., @callback or @function (or its aliases @func or
@method) (including those associated with an @interface).
See the "AST and Selectors" section of our README for more on the expected format.
| Context | ArrowFunctionExpression, FunctionDeclaration, FunctionExpression; others when contexts option enabled |
| Tags | param |
| Aliases | arg, argument |
| Recommended | true |
| Options | contexts |
