Rendering Control Overview

ArkUI uses the build() function of custom components and declarative UI description statements in the @Builder decorator to build the corresponding UI. In declarative description statements, you can use rendering control statements in addition to system components to accelerate UI construction. These rendering control statements include conditional statements that control whether components are displayed, loop statements for repeated content that quickly generate components based on array data, lazy loading statements for scenarios involving a large amount of data, and component rendering statements for hybrid development.
