Summary
A symbol is a reusable object, and an instance is an occurrence of a symbol on the Stage. Repeatedly using instances does not increase the file size and is a good part of a strategy for keeping a document file size small. Symbols also simplify editing a document; when you edit a symbol, all instances of the symbol update to reflect the edits. Another benefit of symbols is that they allow you to create sophisticated interactivity.
