Google Closure Compiler, Handling JSC_INEXISTENT_PROPERTY warning

Question

How can I get rid of the warnings on running the following code through Google Closure Compiler Advance mode?

var defaults = {
    team : 'ABC',
    wr:  'Calvin',
    qb: 'Manning'
};

var config = {};

var setters = {
    team : function(){ return defaults.team},
    wr : function(){ return defaults.wr}
};

for(var i in setters){
    config[i] = setters[i].call();
}


alert( config.team);
alert( config.wr);

Number of warnings: 2

JSC_INEXISTENT_PROPERTY: Property team never defined on config at line 19 character 7
alert(config.team);

   ^
 JSC_INEXISTENT_PROPERTY: Property wr never defined on config at line 20 character 7
 alert(config.wr);


   ^

Found it.

@lends does the trick.

lends tag

var defaults = {
    team : 'ABC',
    wr:  'Calvin',
    qb: 'Manning'
};
var config = {};


var setters = 
/** @lends {config} */
{
    team : function(){ return defaults.team},
    wr : function(){ return defaults.wr}
};

for(var i in setters){
    config[i] = setters[i].call();
}


alert(config.team);
alert(config.wr);
