Definition of var
The var statement declares a variable.
Variables are containers for storing information.
Creating a variable in JavaScript is called "declaring" a variable:
var message;
After the declaration, the variable is empty (it has no value).
To assign a value to the variable, use the equal sign:
message = "Hello";
You can also assign a value to the variable when you declare it:
var message = "Hello";
