The document discusses different types of assets that can be used to build applications faster, including SWCs (Software Component), embedded SWFs (Shockwave Flash), and loaded SWFs. It provides examples of using each type and notes their advantages and disadvantages. SWCs allow for code completion and reuse of existing components but can be larger in file size. Embedded SWFs execute timeline code directly but require two frames. Loaded SWFs have a smaller initial footprint but require more code. The summary recommends using the right tool for the job and thinking ahead about organization and potential issues.
