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.

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.

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. ======================   Some directives in AngularJS ng-app Sorry, blogger still does not support the "pre" tag!. The ng-app directive can be in the 'html' or the 'body' (shown here). ============== When viewed on the browser (in this case Microsoft Edge), the HTML page renders as shown.
