Vue.js Rendering mechanism
summary
Explains how Vue compiles templates into render functions (build-time or runtime) that produce a virtual DOM, then mounts it via a creation pass and updates it via a patching process. Describes compiler optimizations: static hoisting of constant subtrees, collapsing consecutive static nodes into HTML strings, and tree flattening to keep only trackable children. Reveals use of numeric patchFlags: 64 and others embedded in generated code so the runtime skips full diffing and updates only known-changing parts.
