Javascript Factory

Creating variables in JavaScript is most often referred to as "declaring" variables.

You can declare JavaScript variables with the var statement:

After the declaration shown above, the variables are empty (they have no values yet).

However, you can also assign values to the variables when you declare them:

After the execution of the statements above, the variable x will hold the value 5, and carname will hold the value Volvo.

Note: When you assign a text value to a variable, use quotes around the value.
