A Mindless note

Hoard a large amount of money for retirement vs medium amount of money and  keep your cash flow positive?

Yes. This is sad and real. I have used Vue 2 for several projects in the company I previously worked for. I have get used to the component-based, one-way data flow concept in current crop of JS framework. Because new company system already heavily invested in AngularJS. I need to adapt to it. And I try to bring the newer concepts back to the old AngularJS.

Going back to an old reactive JS framework is more difficult than pure JS or jquery. It takes me a few weeks to click. Not to mention the depercation of $scope, the poor performance watchers, the less and less people using AngularJS anymore as community support...

Step 1. Bring back the component based syntax --------

In Vue JS, you declare a component, with props as input parameter, and simply include the components like this inside a template:

``` <my-component :some-prop="acmePropValues"></my-component>

``` There is even a concept called slot (Transclusion) that you can make your components even more reusable.

In AngularJS, the component based and slot concept are already there. But because they are concepts that are being promoted in the later years of AngularJS develop cycle, one from modern JS frameworks need to understand extra concepts to replicate these concepts in AngularJS:

- isolated scopes provided by directive - controller used only from directive

I  have seen a LOT of lines of the existing code base include ngController directly to a page, which means that such controller can exist only once in each page because they share the same scope. These ngControllers are quite unfriendly that they query DOM elements as input parameters, which makes them totally not reusable.

Reference: https://weblogs.asp.net/dwahlin/creating-custom-angularjs-directives-part-6-using-controllers https://www.3pillarglobal.com/insights/angularjs-understanding-directive-scope

Step 2: one-way data flow --------

In VueJS, you can simply do the following in almost anywhere in your component methods to emit anything from a child component to the parent component.

In AngularJS, such concept exists but only in the deprecated $scope $emit and $on. (controllerAs is preferred) So bring back $scope for one way data flow.

Step 3: the slow watchers --------

If you work too hard, you will miss something before you even notice.

This syndrome is an extension of the not-invented here syndrome. The affected feels pressurized when someone else properly did when he thinks it is his original idea and that someone else get 100+ stars in the Github repo.

I have not worked for anyone for almost 2 months now. Here is what I figure out: Unlimited time to do your own business                          to think about your life                             this is so good. Back then, I rely on my sub-conscious to work it out for me. Now I have my day time to help myself too.

Limited time (and budget)         to eat         to have air-condition         to play         to meet others                               you may have unlimited personal time but you are still unable to meet someone as you wish.                           to write                    due to my short attention span, I have a hard time to write things in my mind.

I clearly remembered that I was relieved when I know that I can finally leave that place. Overwhelming by work pressure, I was always tired and could not think properly. Almost a year later, where I am? I found another job, learn something, but I dont like it too much so I quit again. Jobless agains. My thought rewinds to the point, why was I leaving? Is there another way?
