JavaScript Data Types and Variables: Chapter 2 - Learning JavascriptShelley Powers
The programming language does not predefine these data types, but instead, the programmer creates it. Additionally, the composite data types come into existence when the grouping of multiple values happens. Few of the JavaScript supported composite DataTypes are: Object: It is an instance of a cla...
JavaScript - Variables - JavaScript variables are used to store data that can be changed later on. These variables can be thought of as named containers. You can place data into these containers and then refer to the data simply by naming the container.
To answer this seemingly simple question, we must look again at the datatypes supported by JavaScript. The types can be divided into two groups: primitive types and reference types. Numbers, boolean values, and thenullandundefinedtypes are primitive. Objects, arrays, and functions are reference ty...
