The role of import in vue

import Import external modules and components in Vue.js: 1. Import external modules, such as JavaScript libraries or third-party components; 2. Import other Vue components to achieve code modularization; 3. Automatically resolve dependencies , simplify development; 4. The scope is limited to the module, maintaining modularity and avoiding conflicts; 5. Creating a namespace to prevent duplicate name problems.

The role of import in Vue

import is a keyword in Vue.js , used to import external modules or components. Its main function is:

1. Import external modules

Use import to import external modules (such as JavaScript libraries or third-party components) Import into Vue component. For example:

import axios from 'axios';

2. Import components

import can also be used to import other Vue components. This allows developers to break applications into smaller reusable components. For example:

import Header from './components/Header.vue';

3. Resolving dependencies

import will also resolve dependencies in imported modules. This means that when a developer imports a module, it automatically loads all other modules that the module depends on. This simplifies the development process as developers do not have to manually manage dependencies.

4. Scope

# The scope of an import statement is limited to the module in which it is declared. This means that the imported module or component is only available within that module. This helps maintain modularity and avoid naming conflicts.

5. Namespace

#import can also be used to create a namespace to prevent duplicate names with variables and functions in other modules. For example:

import { Vue, Component } from 'vue-property-decorator';

Overall, import plays a vital role in Vue.js because it allows developers to import external modules and components, thus promoting modularization and reuse and dependency management.
