How to easily create a namespace in JavaScript to avoid polluting global space

namespace.js

// Check if the namespace 'KEB' is available globally
if (!KEB) {
	// If it is, then assign an object to the 'KEB' variable, and you have your namespace!
	var KEB = {};
}

// Write a variable (attribute) to the namespace
KEB.name = "KEB";

// Write a function (method) to the namespace
KEB.sayHello = function() {
	console.log("Hello "+KEB.name);
}

// Run the function from the namespace
KEB.sayHello();

// Now wasn't that easy? :D

// You can of course also work directly with the keys and values of the namespace object
