- A JavaScript variable is merely a name for a storage place. Variables in JavaScript are classified as either local or global. 
When declaring a JavaScript variable, there are several guidelines to follow (also known as identifiers). 
1.The name must begin with a letter (a to z or A to Z), underscore (_), or dollar ($) symbol. 
2.After the initial letter, we can include digits (0 to 9), for example, value1. 
3.JavaScript variables are case sensitive, therefore x and X are separate variables.
