What is the Web front-end

The Web front-end is the web page displayed to the user, that is, the front-end part of the website.

The main content of early websites was static, mainly pictures and text, and users' behavior when using the website was mainly browsing. With the development of Internet technology and the application of HTML5 and CSS3, modern web pages are more beautiful, have significant interactive effects, and are more powerful.

The web front-end is mainly aimed at coding and building visible things, that is, the interface for users to interact with, concentrated in a web application or website.

It provides a graphical, easy-to-access and intuitive interface for viewers to find and browse information on the Internet. The documents and hyperlinks organize the information nodes on the Internet into an interconnected system. network structure.

The challenge with front-end web programming is that the tools and technologies used to implement front-end pages change rapidly, so engineers need to constantly pay attention to how the industry is developing (such as ECMAScript 6).

The purpose of designing web pages is to ensure that when users open the site, the information is presented in an easy-to-read and relevant form. The problem that comes with this is that users now use a large number of devices to access the web, and these devices have different screen sizes and resolutions.

Front-end developers need to know how to write logic or code and be able to make the project work in a business environment. Therefore, front-end developers should be able to use version control tools such as GIT. Likewise, he should also be proficient in Continous integration and continuous deployment tools like TeamCity or Jenkins, these are important for developers as they help in managing and automating builds which play a vital role when it comes to development effect.

Why do we need front-end developers?

The front-end is the person responsible for providing visual effects to users. Without a front-end, users would have no idea what to do when looking at numerous APIs.
