If you’re looking for how to document the type of objects in an array, you want something like this:
/**
* @param {String[]} aliases
*/
Here inside curly-braces the String[] is the parameter type: type String as array [].

Parameter Type Information
Use curly-braces around the expected type of the parameter to document this information.
/** * @param {String} userName */ function logIn(userName) { // ... }Use a pipe symbol to document that multiple types are permitted.
/** * @param {String|Number} product */Use the [] notation after a type to indicate an array of those types.
/** * @param {String[]} aliases */
