The difference between js front end and web front end

With the continuous development of Internet technology, front-end development has gradually become an indispensable part of the Internet industry. In front-end development, JS front-end and Web front-end are two common concepts, and what is the difference between the two? This article will analyze this topic.

1. Introduction to JS front-end

JS front-end is JavaScript front-end development, which refers to developers who mainly use JavaScript technology to implement web page functions. JS front-end requires familiarity with the JavaScript programming language, mastering front-end technologies such as HTML5 and CSS3, and being able to use common JS frameworks and libraries for web development. The JS front-end is mainly responsible for web page effect realization, dynamic data interaction, front-end logic design, optimization and other related work.

The main responsibilities of JS front-end development include:

1. Responsible for the realization of web page effects and dynamic data interaction, to achieve highly adaptive and responsive layout of web pages.

2. Write JavaScript code to realize dynamic interaction with web content and related effects.

3. Master JS frameworks and libraries (such as JQuery, Vue, AngularJS, etc.) to improve development efficiency.

4. Reduce the size of web page files and the number of visits as much as possible to improve web page loading speed.

2. Introduction to Web front-end

Web front-end refers to developers who realize web page layout, style and content through HTML and other technologies. The Web front-end needs to master HTML, CSS, JavaScript and other front-end technologies, understand cross-browser compatibility issues, and also need to understand the basic knowledge of the server side, such as basic back-end development languages, etc.

The main responsibilities of Web front-end development include:

1. Responsible for the layout, page style and content implementation of the website web pages.

2. Responsible for optimizing the compatibility of web pages with different browsers, so that the website can be displayed well in various browsers.

3. Be familiar with CSS technology and master CSS preprocessor (such as Sass) development.

4. Basic Web backend knowledge (such as PHP, node.js, etc.).

3. Differences between JS front-end and Web front-end

Although JS front-end and Web front-end are similar, there are differences in responsibilities, work content, and skill requirements. The specific performance is as follows:

1. Differences in responsibilities: JS front-end is mainly responsible for page effect realization, dynamic data interaction, front-end logic design and optimization, etc. The Web front-end is responsible for the layout, style and content implementation of the web page to ensure that the visual effect of the website is more beautiful.

2. Differences in work content: JS front-end needs to be proficient in JavaScript programming language, master front-end technologies such as HTML5 and CSS3, and also need to strengthen the use of JS frameworks, libraries and other tools. The web front-end needs to be familiar with HMTL, CSS and other technologies, and needs to understand CSS preprocessors.

3. Differences in skill requirements: JS front-end needs to be proficient in the JS programming language and understand the use of JavaScript frameworks, libraries and APIs. Web front-end needs to understand the basic knowledge of HTML, CSS, and JavaScript, and have good proficiency in common visual UI layout methods.

4. Summary

In the current Internet era, front-end development has been an industry with strong momentum in recent years. However, with the continuous development of technology, the difference between the two positions of web front-end and JS front-end has gradually become obvious. It should be noted that different companies may have different needs for front-end development positions, so it is very important to accurately grasp the responsibilities and skill requirements of the front-end position you want to engage in.
