You don't need to learn jquery to learn vue

As two commonly used libraries or frameworks in front-end development, Vue.js and jQuery both have a wide range of users. When many developers want to learn Vue.js, they will have a doubt: Is it necessary to learn jQuery to learn Vue.js?

In this article, we will analyze the similarities and differences between Vue.js and jQuery, as well as their usage scenarios and technical features in actual projects, to answer "Do you have to learn jQuery to learn Vue.js?" The problem.

The similarities and differences between Vue.js and jQuery

Vue.js and jQuery are both commonly used libraries or frameworks in front-end development. Although there are similarities between the two, there are also obvious differences. difference.

(1) Data-driven

The applications built by Vue.js are data-oriented and do not require direct manipulation of the DOM like jQuery. By separating business logic, the application logic is clearer and the code is easier to maintain.

(2) Componentization

Vue.js supports component-based development. The application can be divided into multiple small components. Each component is responsible for independent responsibilities, making the logic clearer and the code clearer. Easy to organize. However, jQuery does not have good componentization support.

(3) Real-time response

One of the most significant advantages of the data-driven approach of Vue.js is real-time response. Whenever the data changes, the view automatically updates. In jQuery, operations such as adding or deleting elements on the page need to be completed by manipulating the DOM.

(4) Data binding

Data binding in Vue.js can effectively reduce direct operations on the DOM. Through simple template syntax, you can easily bind data to the view and realize automatic updating of data. But in jQuery, data binding requires manual manipulation of the DOM.

(5) Plug-in support

Unlike jQuery, Vue.js itself has a wealth of plug-ins, and new plug-ins are constantly being added. These plug-ins can extend the functions of Vue.js and improve the maintainability and scalability of the program. jQuery relies on plug-ins to extend its functions, such as form validation, template engines, etc.

(6) Syntax Features

Vue.js uses template syntax. You don’t need to master too much JavaScript to get started quickly. jQuery can be said to be an enhanced version of standard HTML and CSS syntax, and developers need to master more knowledge of JavaScript and DOM operations.

In actual projects, the usage scenarios and technical features of Vue.js and jQuery are also obviously different.

In actual projects, the usage scenarios and technical features of Vue.js and jQuery are also obviously different.

(1) Requirement adaptation

If you need to adapt to the existing jQuery project, then there is no need to learn Vue.js in depth. On the contrary, if it is a new project or the project needs to be refactored, it is recommended to use Vue.js.

(2) Front-end and back-end separation

Vue.js is more suitable for use in projects with front-end and back-end separation. This can more clearly divide the front-end and front-end responsibilities, which is a more advanced development model. . jQuery is more suitable for the traditional back-end rendering page application development model.

(3) Application complexity

When the application complexity is high, the component development model of Vue.js will better meet the project needs. When the development requirements are simple, jQuery's way of operating DOM and event binding is more convenient and faster.

(4) Development Cost

Although Vue.js has a certain learning cost, as the project scale expands and needs change, learning Vue.js can effectively improve development efficiency and save development costs. cost. The learning cost of jQuery is relatively low, but when the project scale is large and the requirements change frequently, the development cost will gradually increase as the project scale expands.

Summary

As commonly used libraries or frameworks in front-end development, Vue.js and jQuery have their own advantages and disadvantages. Vue.js is characterized by data-driven and componentization, which can effectively improve development efficiency and maintainability, and is suitable for more complex projects with front-end and back-end separation. jQuery, on the other hand, features DOM manipulation and is suitable for projects with simple requirements and small project scale.

During the development process, developers should choose appropriate libraries or frameworks for development based on project needs. Regardless of whether you choose Vue.js or jQuery, you need to have basic front-end development skills, including HTML, CSS, JavaScript, etc., which are the foundation of front-end development.
