I've got an array of channels that I want to transform into a single object (channelSettings) with a true / false property for each channel.

I've got it working using the below code but it seems verbose. Is there are way to do it without the temp var? If I can get ride of that, then I could get ride of the self executing function as well.

var channels = [TV, Billboard, Spot TV];





var channelSettings = function() {

    var temp = {};



    channels.map(function(itm, i, a) {

        var channel = itm.toLowerCase().replace( , );

        temp[channel] = false;

    });



    return temp;

}();

I guess I'm trying to get the map function to return an object with properties instead of an array. Is this possible? Is it mis-guided? Suggestions?

This is what I'm hoping it looks like in the end:

var channels = [TV, Billboard, Spot TV];



var channelSettings = channels.map(function(itm, i, a) {

        var channel = itm.toLowerCase().replace( , );

        return ????;

});
