Objects are reusable software components, which allow maximizing usage and increase quality and productivity in applications.

An object in E3 encapsulates or contains three different parts (properties, methods, and events) that can be manipulated to use the advantages of their functionality in an application.

Properties define attributes of an object, such as its appearance on a Screen or its initial value when an application starts.

Methods are functions that perform a specific action in or with an object.

Events are notifications generated by an object in response to a particular occurrence, such as a mouse click or a change in a Tag's value, among others.

One of the most important features when working with scripts in E3 is to consider the separation between processes executed on a Server and those executed on a Client (E3 Viewer).
