Creating a Namespace Using an IFEE □ (Immediate Function Execution Expression -- run immediately, run once etc. ) □ Adds robustness to the ns with this IFEE language feature. □ Use IFEEs to initialize a namespace once with its relevent functionatily. Wrap the code in an IFEE

Creating a Namespace Using IFEE.js

				 var ns;

				        var bmw = new ns.Car("BMW");
				        console.log(bmw.speed); // outputs 0
				        console.log(bmw.type); // outputs "BMW"
				        bmw.drive(80);
				        console.log(bmw.speed); // outputs 80
