Question: What is the role of export default in Vue? Detailed description: export default defines the default export of the component. When importing, components are automatically imported. Simplify the import process, improve clarity and prevent conflicts. Commonly used for exporting individual components, using both named and default exports, and registering global components.

The Vue.js map function is a built-in higher-order function that creates a new array where each element is the transformed result of each element in the original array. The syntax is map(callbackFn), where callbackFn receives each element in the array as the first argument, optionally the index as the second argument, and returns a value. The map function does not change the original array.

In Vue, the change event can be disabled in the following five ways: use the .disabled modifier to set the disabled element attribute using the v-on directive and preventDefault using the methods attribute and disableChange using the v-bind directive and :disabled

The script tag in Vue should be immediately inside the template element <template> to achieve tight coupling between logic and template and ensure the normal operation of the component.

The Java framework and Vue front-end adaptation implement communication through the middle layer (such as SpringBoot), and convert the back-end API into a JSON format that Vue can recognize. Adaptation methods include: using the Axios library to send requests to the backend and using the VueResource plug-in to send simplified API requests.

Vue's async modifier is used to create asynchronous components or methods to achieve dynamic loading of components and execution of asynchronous operations to avoid blocking the main thread.

The render function in Vue.js is responsible for converting component data into virtual DOM, which can improve performance, enable templating, and support cross-platform. Specific functions include: 1. Generating virtual DOM; 2. Improving performance; 3. Implementing templates; 4. Supporting cross-platform.

The function of the setup function in Vue is to initialize component state and logic, including defining responsive data, methods and life cycle hooks. Replaces data(), methods(), computed(), and watch() options in the options API. Provide better performance through responsive handling. Supports Composition API for sharing and reusing logic. Improves testability because logic is separated from template code.
