Comprehensions in JavaScript

Image
Comprehension(s) list(array) is used in many computer languages. What it does is it takes an array and modifies it  to create a new list(array) based on some modifier.

For example if you have a list like this: [ 1,2,3 ],
you can create a new list with each element of list replaced by itself multiplied 3 times like in Example 1

In the second example from Mozilla site, you take an array of lower case letters and use the Javascript string operatory 'toUpper()' to generate a new array with letters of each element capitalized.

There are programs for which you need to pay, which I am not ready, as I do not derive any revenue from what I do. I am looking for free programs.

Progressively Intel XDK has been shifting their focus to mostly Intel IoT devices. The App Designer support does not exist anymore except for a few features in the interface. The Interface as you knew it is now mostly geared for IoT devices. Intel XDK forum suggests that there are more tools freely available (on the Internet) that may do equally well and a strong recommendation for using Cordova CLI.

Well one cannot expect a tool to live eternally and things do change. What is needed on the part of developers\users is to turn somewhat nomadic and look for new pastures.

AngularJS Directives that you should know

AngularJS directives are extensions of HTML markups. They can be attributes, element names, CSS class etc. AnuglarJS script reference is important and the script can be found here:

https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"
The above script reference needs to be added to your hTML page.

You can find the whole list of directives here:
https://docs.angularjs.org/api

Here is the usage of some directives placed in a html page that can be displayed on your localhost (in this case the IIS in Windows 10). Place this code with a suitable name in the inetpub / wwwroot directory.
