To link to "something else" in JSDoc, including another method, use the {@link ...}
tag. In your case, you would use:
// See also {@link xyz}
You'll then be able to Ctrl+click on xyz
in WebStorm.
The JSDoc terminology for that "something else" is "namepath". Below follows the original answer by Andrew, which explains namepaths.
Basic Syntax Examples of Namepaths in JSDoc 3
myFunction
MyConstructor
MyConstructor#instanceMember
MyConstructor.staticMember
MyConstructor~innerMember // note that JSDoc 2 uses a dash
Special cases: modules, externals and events.
/** A module. Its name is module:foo/bar.
* @module foo/bar
*/
/** The built in string object. Its name is external:String.
* @external String
*/
/** An event. Its name is module:foo/bar.event:MyEvent.
* @event module:foo/bar.event:MyEvent
*/
For easy coding, I sometime use markdown
style in comment:
// see function name in file dir/file.name
// see the method [named of the method](file-name #method name)
