Many novices who want to enter the IT industry will be advised to learn Web front-end. Why? What do the front-end, back-end, and full stack refer to? What are the corresponding job requirements?
As the saying goes, "knife sharpening and not chopping wood by mistake". Only by understanding the definition of the job types, functions and skills requirements of the Internet can you learn more efficiently and planly, and thus move towards the goal of Internet business. Below, the editor of Qianfeng Chongqing Web front-end will briefly explain the front-end, back-end and full stack from the perspective of concepts and technical content requirements.
One, front-end development
Front-end development mainly involves websites and apps, what users can see from the browser or on the App screen. Simply put, everything you can see from the browser or App screen belongs to the front end.
1. Skills and tools
Front-end development is to create the code behind the user-facing part of the website mentioned above, and build an immersive user experience by establishing a framework. In order to achieve this goal, development requires proficient use of the following languages, frameworks, and tool libraries:
● Three languages: HTML, CSS, and Javascript;
● In addition, it is also important to master tool libraries such as jQuery and LESS, which can help developers code in a more efficient way;
● Many front-end development posts also require experience in the use of Ajax methods, which can help you use Javascript to pull data from the server in the background and assist in dynamic page loading.
Using these technologies, front-end developers can connect the bridge between website designers and back-end developers. They can provide user experience analysis, build models and wireframes, and make suggestions to the design team. They can give life to the service applications written on the backend, enhance the style, and create a sense of beauty.

Two, back-end development
Back-end development is "server-side" development, mainly involving the "back-end" of the software system. For example, the server used to host website and App data, and the middleware placed between the back-end server and the browser and App, all belong to the back-end. Simply put, those things that you can't see on the screen but are used to support the front end are the back end.
1. Skills and tools
In order for servers, applications, and databases to interact with each other, back-end engineers need to have the following skills:
● Server-side languages for application construction: PHP, Ruby, Python, Java, .Net, etc.;
● Data related tools: MySQL, Oracle, SQL Server, etc.;
● PHP framework: Zend, Symfony, CakePHP, etc.;
● Version control tools: SVN, CVS, Git, etc.;
● Be proficient 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 formulate the most effective and streamlined plan to achieve it.
Three, full stack development
Full-stack development, as the name suggests, can do both front-end and back-end tasks. The "stack" here refers to the various layers of web applications, that is, such developers have multi-level technologies including server programs, data structures and models, user interfaces, user experience, etc., and have mastered everything needed in the business. One stage of technology.
1. Skills and tools
Full-stack developers can basically describe them as know-how. Enterprise requirements for full-stack development positions include the following:
● Use HTML, Java, JavaScript to write optimized front-end code
● Create and use API and write backend code in Ruby, Python/Java
● Use system infrastructure, including hardware and operating system
● Understand, create and query databases
● Project management and customer coordination
The specific tools depend on the project and customer needs. Full-stack developers need to have sufficient understanding of every level of the Web architecture: build and configure a Linux server, write server-side APIs, use client-side Java code to drive applications, and design The stuff is transformed into actual CSS code.
While mastering and using a large number of tools, full-stack developers need to quickly allocate server-side and client-side tasks, provide solutions, and compare the advantages and disadvantages of different solutions.
However, full-stack development does not mean that you do the entire project alone. In most cases, full-stack developers will still spend their main energy on the front-end or back-end development process. But unlike other developers, full-stack developers can cross the boundaries of the project when needed, such as improving the user experience while optimizing the database model.
