3C++
Difficulty: ★★★★ Popularity: ★★★★
C++ is an object-oriented programming (OOP) language widely regarded as the most outstanding language for large-scale application construction.C++ is a superset of the C language.
Uses: Software development, search engines, operating systems, video games
Advantages:
1, Important skill: Mastering C and C++ can help you stand out among many developers. By mastering C/C++, you will gain a deep understanding of memory management mechanisms in languages like Java or Python, and learn how to avoid various common pitfalls and challenges.
2, Flexible adjustment space: C++ allows you to flexibly adjust your applications and fully utilize the computer’s performance. Compared to Java/C++, the programming process is not user-friendly, but we can use it to achieve everything.
Disadvantages:
1 Difficult learning curve: C++ is very difficult to learn, but once mastered, you will directly reach the pinnacle of the programmer’s hierarchy.
2 Extremely large system: C++ is vast and has many complex functional interactions. No developer can use all the building components it offers, but we can fully utilize our intelligence to choose the correct subset of functions.
4Python
Difficulty: ★★ Popularity: ★★★★★
Python is a server-side interpreted open-source non-compiled scripting language that can be used independently or as part of frameworks like Django.
Uses: Web development, video game development, desktop GUI software development.
Advantages:
1, Easy to learn: Python is known for being the easiest programming language to master, making it very popular.
2, Libraries: A wide range of tools and libraries can help you easily complete construction tasks.
3, Internet of Things: Python has further developed with the popularity of IoT technology. Currently, new platforms like Raspberry Pi have made it the basis for development.
Disadvantages:
1, Speed: As an interpreted language, its speed is often lower than that of compiled languages.
2, Mobility: Python has a relatively intuitive performance in mobile computing, and mobile applications developed using Python are very rare.
3, Design: Python has some design issues, as it is a dynamically typed language, leading to a need for more testing and certain errors that only appear in specific runtime environments.
5PHP
Difficulty: ★★★ Popularity: ★★★★
PHP is a server-side scripting language with a large and active community, primarily aimed at web development but also serves as a general-purpose programming language.
Uses: WordPress plugins, Web development, creating pages with database functionality.
Advantages:
1, Easy to use and feature-rich: It is a server-side scripting language suitable for web development and general purposes, easy to quickly get started.
2, Large community: PHP has a large active community. Most challenges faced by web developers have ready-made solutions.
3, Database: Can work smoothly with various databases, file systems, and images.
Disadvantages:
1, Low learning threshold: Due to the low learning threshold, there are many inexperienced developers in projects, and some open-source codes have existed for over a decade.
2, Speed: PHP is an interpreted language, and its code runs slower than most of its programming language competitors.
3, Error handling mechanism: PHP has a poor error handling mechanism, especially compared to other programming languages, mainly due to its long development history and the need to support many legacy features.
6JavaScript
Difficulty: ★★ Popularity: ★★★★
JavaScript is the most efficient client-side scripting language, meaning that JavaScript code is written into HTML pages. When users request the HTML page through internal JavaScript, the script is sent to the browser, and the browser decides the next action.
Uses: Front-end websites, analytics, functionality controls, Web interactions
Advantages:
1, Speed: As a client-side scripting language, any code function within JavaScript can run immediately without waiting for server connections and responses, making its speed outstanding.
2, Ease of learning: JavaScript is relatively easy to learn and use. Mastering JavaScript means becoming a full-stack engineer capable of developing web pages, backends, and mobile applications.
3, Simplicity: JavaScript can collaborate smoothly with many other languages and can be used in various applications. Unlike PHP or SSI scripts, JavaScript can be inserted into any webpage without considering specific file extensions.
Disadvantages:
1, Security: Since code executes on the user’s computer, it can sometimes be exploited by malicious activities. For this reason, some users choose to disable JavaScript.
2, End-user dependency: JavaScript can sometimes be interpreted differently across different browsers. Compared to server-side scripts that can always provide the same output, the predictability of client-side scripts like JavaScript is relatively poorer. However, this issue is not very severe as long as we thoroughly test scripts across all major browsers.
7C#
Difficulty: ★★★ Popularity: ★★★★
This is a powerful and flexible programming language. Like other programming languages, it can be used to create various applications. In fact, the functionality of C# is only limited by our imagination. The language imposes no restrictions on developers’ operations and can be used to deliver dynamic websites, development tools, and even compilers.
Uses: Windows applications, enterprise-level business applications, software development.
Advantages:
1, .Net library: Fully integrated .Net libraries provide excellent functionality and support library access capabilities.
2, Convertibility: Based on C, thus C# structures can be transferred to Java, Objective-C, PHP, and C++ and other language forms.
3, High demand: C# and Java are currently the most in-demand software development skill combinations in enterprises.
Disadvantages:
1, C# is not the most suitable programming language for beginners to learn as it has a very steep learning curve.
2, Poor cross-platform capability: Due to integrating .Net, it lacks cross-platform capabilities.
From the above comparison, it is not difficult to see that each programming language has its advantages and disadvantages. When choosing a programming language, we mainly consider several key points.
1, For building web pages: Recommended: HTML, CSS, PHP
