Variable vs Object?

[Dan Ebberts]

A variable is just a named location where you store and retrieve a value.

An object is a collection of data and functions which you access using the dot(.) notation convention. For example, to use the sine function of JavaScript’s Math object, you would do this:

Math.sin(your_angle)

Scope is within the function where it is declared (or global if delcared outside all functions).

A good JavaScript reference helps.

Thanks Dan!

What I’m thinking of is- If you wanted to declare a global variable within a function, could you just use an object instead of a variable?
