Commonly used modifiers in Vue.js
Modifiers are special suffixes used to modify the behavior of instructions in Vue.js. They can be added to the end of a directive to specify additional functionality.
Commonly used modifiers:
1. .lazy
- Delays the execution of the instruction until the element enters DOM.
-
Usage:
v-model.lazy
、v-if.lazy
2 . .memo
- Cache the calculation results of instructions to prevent repeated calculations in subsequent renderings.
-
Usage:
v-bind:class.memo
##3. .number
- Force the expression to a number for numeric input.
- Usage: v-model.number
Trim spaces in input values.
- Usage:
- v-model.trim
Default behavior of blocking events.
- Usage:
- v-on:click.prevent
##6. .stop
Prevent events from bubbling.
- Usage:
- v-on:click.stop
-
##7. .once
Execute the command only once.
Usage:- v-on:click.once
-
##8. .self
Usage:
- v-on:click.self
-
##9. .capture

Vue.js is loved by developers because it is easy to use and powerful. 1) Its responsive data binding system automatically updates the view. 2) The component system improves the reusability and maintainability of the code. 3) Computing properties and listeners enhance the readability and performance of the code. 4) Using VueDevtools and checking for console errors are common debugging techniques. 5) Performance optimization includes the use of key attributes, computed attributes and keep-alive components. 6) Best practices include clear component naming, the use of single-file components and the rational use of life cycle hooks.

Vue.js is a progressive JavaScript framework suitable for building efficient and maintainable front-end applications. Its key features include: 1. Responsive data binding, 2. Component development, 3. Virtual DOM. Through these features, Vue.js simplifies the development process, improves application performance and maintainability, making it very popular in modern web development.

Vue.js and React each have their own advantages and disadvantages, and the choice depends on project requirements and team conditions. 1) Vue.js is suitable for small projects and beginners because of its simplicity and easy to use; 2) React is suitable for large projects and complex UIs because of its rich ecosystem and component design.

Vue.js improves user experience through multiple functions: 1. Responsive system realizes real-time data feedback; 2. Component development improves code reusability; 3. VueRouter provides smooth navigation; 4. Dynamic data binding and transition animation enhance interaction effect; 5. Error processing mechanism ensures user feedback; 6. Performance optimization and best practices improve application performance.

Vue.js' role in web development is to act as a progressive JavaScript framework that simplifies the development process and improves efficiency. 1) It enables developers to focus on business logic through responsive data binding and component development. 2) The working principle of Vue.js relies on responsive systems and virtual DOM to optimize performance. 3) In actual projects, it is common practice to use Vuex to manage global state and optimize data responsiveness.

Vue.js is a progressive JavaScript framework released by You Yuxi in 2014 to build a user interface. Its core advantages include: 1. Responsive data binding, automatic update view of data changes; 2. Component development, the UI can be split into independent and reusable components.

Netflix uses React as its front-end framework. 1) React's componentized development model and strong ecosystem are the main reasons why Netflix chose it. 2) Through componentization, Netflix splits complex interfaces into manageable chunks such as video players, recommendation lists and user comments. 3) React's virtual DOM and component life cycle optimizes rendering efficiency and user interaction management.

Netflix's choice in front-end technology mainly focuses on three aspects: performance optimization, scalability and user experience. 1. Performance optimization: Netflix chose React as the main framework and developed tools such as SpeedCurve and Boomerang to monitor and optimize the user experience. 2. Scalability: They adopt a micro front-end architecture, splitting applications into independent modules, improving development efficiency and system scalability. 3. User experience: Netflix uses the Material-UI component library to continuously optimize the interface through A/B testing and user feedback to ensure consistency and aesthetics.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
