does @var inside javascript comment contains any meaning?

Question

in some strong and advanced files on GitHub, you find something like this:

/**
* The router is in charge of handling `yo` different screens.
* @constructor
* @param {Environment} env A yeoman environment instance
* @param {Insight} insight An insight instance
* @param {Configstore} [conf] An optional config store instance
*/

Does this comment contains any effect on the code or it is a normal comment??
