Front-end development engineer is a very new profession. It really started to receive attention domestically and even internationally in 2005. It refers to the abbreviation of Web front-end development engineer. Web front-end development evolved from art, and the name has obvious characteristics of the times. In the evolution of the Internet, in the Web 1.0 era, the main content of the website was static, and users' behavior when using the website was mainly browsing. With the further development of the Internet, front-end development engineers have become a very sought-after talent in the market. Many students, including those who used to do UI, Java, or have no basic knowledge of IT, want to learn front-end.
