I'm learning Angular and in all the resources I've used so far I saw this in the app.js file:
(function () {
\\\myAngularModules
})();
The most commonl explainantion is an unhelpful "it's just good practice".
Questions:
Please give examples where possible.
This is what is known as an immediately invoked anonymous function (IIFE). It allows us to create a new function scope and immediately run the code so that no variable or other items we create "leak" out and manipulate the global scope.
Leaking of your code into the global can impact other modules or 3rd party code. This also helps protect your code by making you think about what objects you are using that are not declared in your local scope.
