This article mainly introduces "what are the differences between web front-end development and back-end development". In daily operation, I believe that many people have doubts about the differences between web front-end development and back-end development. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what are the differences between web front-end development and back-end development?" Next, please follow the editor to study!

1. Frontend development:

The "front end" of the site is the part that interacts directly with the user, including all the visual content you come into contact with when browsing the web-from fonts to colors, as well as drop-down menus and sidebars. These visual contents are all rendered by the browser after parsing, processing and rendering the relevant HTML, CSS and Java files. Front-end development is to create the code behind the user-facing part of the site mentioned above and build an immersive user experience by building a framework. To achieve this goal, developers need to be proficient in the following languages, frameworks, and tool libraries.

2. Backend development:

In order for servers, applications, and databases to interact with each other, back-end engineers need server-side languages for application construction, data-related tools, PHP framework, version control tools, and proficiency in using Linux as a development and deployment environment. Back-end developers use these tools to write clean, portable, well-documented code to create or update Web applications. But before writing code, they need to communicate with customers, understand their actual needs and translate them into technical goals, and develop the most effective and streamlined solutions to achieve them.

3. The difference between front-end development and back-end development:

(1) different ways of display

The front-end refers to the user-visible interface, and the front-end page of the website is the page development of the web page, such as special effects, layout, pictures, video, audio and so on. The front-end work is to design the effect map of the art design into a web page that the browser can run, and cooperate with the back-end to do the visual work such as data display and interaction of the web page.

The back end refers to something invisible to the user, usually interacting with the front end engineer and saving and reading the website data. relatively speaking, the back end involves much more logic code than the front end, and the back end considers the implementation of the underlying business logic, the stability and performance of the platform, and so on.

(2) different technologies are used.

The technologies used in front-end development include but are not limited to html5, css3, javascript, jquery, Bootstrap, Node.js, Webpack,AngularJs,ReactJs,VueJs and so on.

Back-end development takes java as an example, mainly including but not limited to Struts spring springmvc Hibernate Http protocol Servlet Tomcat server and other technologies.

For example, to make a login page, the user enters the account password on the front page, and then clicks the login button with the mouse. At this time, the front end will send the account password to the back end for processing through the request API. The back end will first check whether the account exists. If it does not exist, it will return a message similar to this to the front end: "the account you entered does not exist, please re-enter it." When the user re-enters the account, the backend queries that the account exists and the password is correct, then the backend returns the information of successful login to the front end. The problems in modern computer field, such as large-scale load, massive data processing, real-time computing are also back-end, and the front end is concentrated in the presentation layer.

(3) the direction of thinking is to interact differently with users.

The first paragraph mainly considers how to make users feel more comfortable, taking into account the interface layout, interaction, page loading speed and so on, mainly in favor of the part visible to the user, browsing web on the client (pc, mobile phone, pad).

The back-end is more concerned with business logic, database table structure design, server configuration, load balancing, data storage, cross-platform API design and so on, and more about the parts that users can not see, to ensure the rigor of business logic processing data and the performance of data throughput.

At this point, the study on "what is the difference between web front-end development and back-end development" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
