6. Hierarchical internal modules

The Vue 3.0 core is still available through a simple <script> tag, but its internal structure has been completely rewritten as a set of decoupled modules. The new architecture provides better maintainability and allows end users to reduce runtime size by half through tree shaking.

The modules are as follows:

Function points provided by the module:

1. Compiler support for building Custom AST transformations (e.g., build-time i18n)

WebGL or Terminal) custom renderer. The default DOM renderer is built using the same API. 3. The functions exported by the @vue/reactivity module can directly access the Vue

reactive system and can be used as an independent package. It can be paired with other template solutions such as

lit-html and can even be used for non-UI scenarios. 7.composition-api design purpose

Aims to solve the difficulties of using Vue in large applications.

The Composition API is built on top of the reactive API, enabling logic composition and reuse similar to React hooks, more flexible code organization patterns, and more reliable type inference compared to the 2.x object-based API.

8. Performance improvement (relative to Vue2)

Through tree shaking (reduced up to 41% of resource size)Initial Rendering (up to 55% faster)

Memory footprint: (up to 54% faster)

You can change the context of this using methods such as call(), apply(), and bind(). These methods call the function using the given this value and parameters. JavaScript is an excellent programming language. A few years ago, this sentence was
