What are the differences and requirements between web front-end development, back-end development, java programmer and mobile development?

First of all, from the technical structure, Web front-end development involves Html, CSS, JavaScript and many front-end development framework technologies. The back-end development technology mainly completes the processing of business logic, involving resource scheduling such as storage management, security management and concurrent processing. There are many programming languages that can be used for back-end development, including Java, Python, PHP, C#, Go and so on. Mobile development involves Android development, iOS development and specific development required by various mobile devices. Android development can use Java or kotlin, iOS development can use OC or swift, and mobile development often needs to master JavaScript language.

Driven by the current cloud computing technology, full-stack front-end development is an obvious development trend, and the working boundary of front-end development posts is also expanding, gradually forming the concept of "big front-end" including Web front-end development, back-end development (part), mobile development and big data display development. Judging from the current employment situation, the employment prospect of front-end development is still good, but enterprises also put forward more requirements for the knowledge of front-end programmers.

At present, driven by big data, cloud computing and artificial intelligence, the development of back-end programmers has two directions, one is the direction of full-stack programmers, and the other is the direction of R&D programmers. For back-end programmers with weak basic subjects (mathematics), if they want to improve their post competitiveness, they can consider developing to full-stack programmers. Java full-stack development is a good choice. For programmers with solid basic disciplines and strong R&D ability, they can take the R&D route in the era of industrial Internet to enhance their post competitiveness and career life cycle.

Finally, for junior programmers, if they want to go further in the field of technology research and development in the future, they can consider studying for graduate students.

I have been engaged in the Internet industry for many years, and I am currently a graduate student in computer science. My main research direction is big data and artificial intelligence. I will write some articles on internet technology one after another, and interested friends can pay attention to me. I believe I will gain something.

If you have questions about the Internet, big data, artificial intelligence, or postgraduate entrance examination, you can leave a message in the comment area!
