Have a two sources:

file1:
------------------------------
/**
 * @constructor
 * @returns {Man}
 */
function Man (fName, sName) {
    var firstName = fName;
    var secondName = sName;
    
    this.getFirstName = function () {
        return firstName;
    }
    
    this.getSecondName = function () {
        return secondName;
    }
    
    
}
-------------------------------
file2:
-------------------------------

var roman = new Man("Roman", "Php");

console.log();  
with(roman) {
   console.log(getFirstName()); 
}

-------------------------------

The Goto declaration doesn't work when you invoke ctrl+click action over the getFirstName() function in second file.
