Façade pattern in JavaScript by Addy Osmani

facade.js

var module = (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"
module.facade( {run: true, val:10} );
