Facade pattern

facade.js

var myModule = (function() {
 
    var _private = {
        i: 5,
        get: function() {
            console.log( "current value:" + this.i);
        },
        set: function( val ) {
            this.i = val;
        },
        run: function() {
            console.log( "running" );
        },
        jump: function(){
            console.log( "jumping" );
        }
    };
 
    return {
 
        facade: function( args ) {
            _private.set(args.val);
            _private.get();
            if ( args.run ) {
                _private.run();
            }
        }
    };
}());
 
 
// Outputs: "current value: 10" and "running"
myModule.facade( {run: true, val: 10} );
