This document outlines the architecture and mental model for packages/core , the heart of the Angular framework. packages/core contains the runtime logic for Angular. Its primary responsibilities are: The rendering engine (located in packages/core/src/render3 ) uses an instruction-based approach. Instructions : The Angular compiler transforms templates into a sequence of instruction calls (e.g., ɵɵelementStart , ɵɵtext , ɵɵproperty ). These instructions are executed at runtime to create and update the view. LView (Logical View) : An array containing the state of a specific view instance. It holds: TView (Template View) : An array containing the static structure of a view. It is shared across all instances ( LView s) of the same component/template. It holds: Memory Layout : LView and TView are parallel arrays.
