Should I learn front-end, back-end or full-stack programming?
As a developer, you may be thinking: What will be the best software development technology and programming language in 2019? How are they used in software development? If you're thinking about this, you've come to the right place.
This article will compare front-end and back-end development technologies, starting with the basics, and then gradually comparing their differences, such as the requirements for development skills. , development potential, career development and salary, etc.
1. What is front-end development?
Front-end development mainly involves websites and apps, what users can see from the browser or the App screen. Simply put, everything you can see from the browser or app screen belongs to the front end. (Recommended: WEB front-end development video tutorial)
Front-end of website and mobile app
Let’s take the webpage you are browsing now as an example . The content on the web page, the images, the gaps between paragraphs, the icons in the upper left corner, the notification button in the lower right corner, all these things belong to the front end.
The front-end of the mobile app is the same as the website. For example, the content, buttons, and pictures you see all belong to the front end. In addition, because the screen of a mobile device is touchable, the application's responses to various touch gestures (such as zoom in/out, double-click, slide, etc.) also belong to the front end, and they are the active part of the front end.
These things are developed by front-end developers who use development technologies such as Ionic, Swift, Kotlin, Bootstrap, Angular, Vue, jQuery, React.js, etc. We will introduce more about these development techniques later.
Front-end of the Internet of Things
Any device that can connect to the Internet is an Internet of Things device. You might be wondering what the front end of an IoT device would look like. Any kind of smart device, such as smart refrigerators, remote POS machines, smart watches, smart wallets, they all need to provide some kind of interface so that users can operate these devices. Therefore, this interface is an interactive medium, and the elements that make up this interface are the front-end of the Internet of Things.
But strictly speaking, IoT devices do not have a real front end. But they all have firmware installed, similar to the front-end of a mobile app. These firmwares can be developed in various programming languages such as C, C, Lua, Python or JavaScript.
2. What is back-end development?
Back-end development is "server-side" development, which mainly involves the "back-end" of the software system. For example, servers used to host website and app data, and middleware placed between back-end servers and browsers and apps, they all belong to the back end. Simply put, the stuff you don’t see on the screen but that is used to power the front end is the backend. (Recommended: Backend development video tutorial)
Backend of website and mobile app
The backend of website involves setting up server, saving and Get data and the interface used to connect to the front end. If front-end developers care about the appearance of the website, then back-end developers care about how to improve the speed, performance and responsiveness of the website through code, API and database integration.
Similar to the front-end, the back-end of a mobile app is the same as the back-end of a website. You have these options for building a backend for your mobile app: cloud platforms (AWS, Firebase), your own servers, or MBaaS (Mobile Backend as a Service).
Back-end development uses Ruby, Apache, Nginx, PHP, MySQL, MongoDB and other technologies. We will introduce more about these development techniques later.
Backend of the Internet of Things
The cloud platform is an important component of the backend of the Internet of Things. There is evidence that most IoT devices rely heavily on cloud servers through which they upload, process and download data.
The backend of high-end IoT solutions even involves artificial intelligence and machine learning.
Backend platforms for IoT projects include Amazon IoT, Google Cloud, MQTT Broker, IFTTT, and more.
3. So what are the differences between front-end and back-end?

4. Which one is better, front-end or back-end developer?
Whether you want to do front-end development or back-end development, in addition to technical aspects, you also need to see what is more important to you.
If aesthetics and product feel are more important to you, then you may be inclined to choose front-end technology. If your focus is on making your website, application, or software more efficient and responsive, then your goal may be back-end development.
A big part of what a front-end designer does is making what the user sees on their mobile or PC screen look great and be easy to use. In contrast, backend developers only care about writing clean code.
If you are trying to decide between front-end and back-end that one is better than the other based on what is said above, then this in itself is a wrong assumption. In fact, they are all irreplaceable and equally important when building a website or application.
Some people are gifted with visuals, while others are good at solving problems through logic and technology. Apple is what it is today thanks to Steve Jobs (the front-end visionary) and Steve Wozniak (the back-end genius).
5. Front-end and back-end developers

Through these points, you can get a comprehensive understanding of the skills of back-end and front-end developers.
Job Titles for Front-End and Back-End Developers
There are many job opportunities for developers, and depending on your specific expertise, experience, and interests, you can apply for one of the following End or front-end development positions.

6. What is full-stack development?
Some people can do both front-end and back-end development, they are called full-stack developers.
Becoming a full-stack developer or hiring a full-stack developer has both advantages and disadvantages. Although the number of developers can be reduced to half of the original number, their level has also been reduced accordingly. A developer who specializes in front-end or back-end development will always know more about a single area than a developer who knows both areas.
There are many technology development stacks similar to the full stack, such as MEAN stack, LAMP stack, .NET stack, Python-Django stack, ROR stack, etc. Developers are free to choose to become experts in these technology stacks.

Apr 26, 2024 pm 04:33 PM
How to remove duplicate values from PHP array using regular expressions: Use regular expression /(.*)(.+)/i to match and replace duplicates. Iterate through the array elements and check for matches using preg_match. If it matches, skip the value; otherwise, add it to a new array with no duplicate values.
What is programming for and what is the use of learning it?

Use golang's error wrapping and unwinding mechanism for error handling
Apr 25, 2024 am 08:15 AM
Error handling in Go includes wrapping errors and unwrapping errors. Wrapping errors allows one error type to be wrapped with another, providing a richer context for the error. Expand errors and traverse the nested error chain to find the lowest-level error for easy debugging. By combining these two technologies, error conditions can be effectively handled, providing richer error context and better debugging capabilities.

Demystifying C: A Clear and Simple Path for New Programmers
Oct 11, 2024 pm 10:47 PM
C is an ideal choice for beginners to learn system programming. It contains the following components: header files, functions and main functions. A simple C program that can print "HelloWorld" needs a header file containing the standard input/output function declaration and uses the printf function in the main function to print. C programs can be compiled and run by using the GCC compiler. After you master the basics, you can move on to topics such as data types, functions, arrays, and file handling to become a proficient C programmer.
