The four types of basic data structures supported by JavaScript are: array lists, maps, records and JSON tables. The following list provides a summary:
-
Array lists, such as
["one","two","three"], are special JS objects called 'arrays', but since they are dynamic, they are rather array lists as defined in the Java programming language. -
Maps are also special JS objects, such as
{"one":1,"two":2,"three":3}, as discussed below.

In all application domains, there are enumeration datatypes that define the
possible values of enumeration attributes. We show how to
implement an enumeration in the form of a special JavaScript object definition
using the Object.defineProperties method.

Where is the "model" in AngularJS? The answer to this question is:
AngularJS does not work with a real model but just with a view model. Therefore, it shouldn't be called an MVC framework, and neither an MVW nor an MV* framework, but rather a View-Model-Whatever (or VM*) framework.

While date/time information items have to be formated as strings in a
human-readable form on web pages, preferably in localized form based on the
settings of the user's browser, it's not a good idea to store date/time values
in this form. Rather we use instances of the pre-defined JavaScript class
Date for representing and storing date/time values.

In most apps we have some form of data management where data is represented in
tables such that table rows correspond to objects, anf the table schema
corresponds to the objects' type. When building a front-end web app
with JavaScript, the simplest approach for persistent data storage is using
JavaScript's localStorage API, which provides a simple key-value
database, but does not support database tables. So, the question is: how can we
store and retrieve tables with Local Storage?

IoT (Internet of Things) applications are now accessible to almost anyone which likes the idea of creating DIY projects by putting hardware components (sensors, actuators and HID devices) along with software components and Web technologies (and not only).

In
summary, the answer to this question is: because unlike the general concept of
an object type or class, the general concept of an association, as defined by
UML, does not have a direct computational counterpart, neither in common
object-oriented (OO) programming languages, nor in SQL.

In standard OO, as defined by UML, and instantiated by Java, there is a certain concept of object. What's the difference between this classical concept of objects and a JavaScript object?
