Far from being dead, AngularJS is incorporating new functionality that keeps it a solid alternative to the newer frameworks that have appeared. This is great news for those developers (like me!) that started using Angular in their current projects from before the 1.0 days.
With that great news comes a few caveats. Consistency has never been a strong suite of Angular 1.x and often it can be unclear if the new features will work correctly within code that follows the older recommended way of doing things. I recently had just that question about the
$onInit callback introduced in Angular 1.5 that is a requirement in Angular 1.6.
The sample code shows that in almost every case where you use a
Controller, you can use the
$onInit callback. This includes using
Controllers on elements,
Controllers defined with
ControllerAs, and of course
Components. The one case it does not work is
Controllers defined in routes used by
ngRoute. No surprise that the Angular router is the odd ball out. Unfortunately this is not something the
ngRoute team appears to want to remedy.
This means that if you have pre Angular 1.5 code and want to upgrade to Angular 1.6, you can and should use
$onInit everywhere except for
Controllers that are used for routes, which you will have to keep using the previous way. AngularJS always has a way of keeping developers on their toes.

Another new Manager Challenge: Managers Have a More Stakeholders
Bad managers never shift from the mindset of an individual contributor. Great managers broaden the number of stakeholders when making decisions.
Self-Evaluating Success as a Manager
In the first part of my series on understanding the difference between management and contribution, I focus on the challenges of evaluating success.
Understanding the difference between contributing and managing
There's a large disconnect between the importance of managers and their broader perception. Management requires a different way of thinking than being an individual contributor.
