Do not declare code in the global namespace directly

Do not declare code in the global namespace directly. Instead consider using the $_global_ namespace pattern with Namespace registration, this will ensure correct execution with the MDS garbage collector

Type JavaScriptFile

Bad Practice

var globalFooAddition = function(foo) {
  return foo + 1;

Good Practice
// Method accepts whole namespace chain, registers Namespaces and creates objects
MyApp.fooAddition = function(foo) {
  return foo + 1;
