What technologies does the web front-end include?

Before we know what a web front-end is, let’s first understand what a web front-end engineer does? This article will tell you what technologies the web front-end includes and what it is.

Web front-end development engineer, whose main responsibility is to develop client products using various web technologies such as (X)HTML/CSS/JavaScript/Flash. Complete the development of the client program (that is, the browser side), develop JavaScript and Flash modules, and combine the background development technology to simulate the overall effect, carry out Web development that enriches the Internet, and is committed to improving user experience through technology.

What is web? The web is the World Wide Web. A thorough explanation of this term would require some space. Let me summarize it in one sentence. It is a globally recognized protocol, an information system, and must comply with this protocol in order to access the Internet. Web front-end is actually front-end, or front-end technology, front-end development. These terms actually mean the same thing. The tools used in front-end web programming can be used for front-end programming, and understanding what tasks the tools are best for can help produce a high-quality, scalable site.

1. Hypertext Markup Language (HTML)

HTML is the skeleton of any web page engineering program. Without it, web pages would not exist. Hypertext markup language can provide the overall appearance of the site. HTML was developed by Tim Berners-Lee. As HTML evolved, many versions were produced on the World Wide Web. The latest version of Hypertext Markup Language is called HTML5 and was launched by W3C on October 28, 2014.

This version includes new and efficient ways to transfer elements such as audio and video files. H5 is very popular among front-end engineers. Compared with older versions, HTML5 has many features. With the development of HTML, a revolution occurred on the Internet.

2. Cascading Style List (CSS)

CSS controls the appearance of the site, giving the site its own unique appearance. Its implementation is to ensure that the style list precedes other style rules and is affected by other input forms, such as screen size and resolution.

3. JavaScript

JavaScript (JS for short) is a scenario-based imperative language (different from the declarative language of HTML), used to convert static HTML interfaces into Dynamic. JS code can use the Document Object Model (DOM) provided by the HTML standard to manipulate web pages based on events, such as user input.

JS uses a technology called asynchronous JavaScript and XML (AJAX). JS code can also dynamically change the content of the web page (independent of the original HTML page), and can also respond to server-side requests. Events add truly dynamic features to the web experience.

There are many popular development frameworks in JS that help developers quickly build web pages. For example, Vue.js, Angular, and React are all very popular frameworks and have a large number of loyal users.

4. Operating system

Understanding the basic knowledge of Unix and Linux is beneficial to developers.

5. Network server

Understand the Web server, including basic configuration of Apache, mastering htaccess configuration skills, etc.
