3.5. Objects

An object is a collection of named values. These named values are usually referred to as properties of the object. (Sometimes they are called fields of the object, but this usage can be confusing.) To refer to a property of an object, you refer to the object, followed by a period and the name of the property. For example, if an object named image has properties named width and height, we can refer to those properties like this:

image.width
image.height
