Postscript: This comic mainly aims to popularize the development history and application scope of programming languages. CLanguage/C++ has always been the top choice for system-level programming, competing in fields such as operating systems, compilers, networks, databases, and high-performance server-side software. Perhaps in the future, Rust might pose a threat to them. In the web programming domain, there is a flourishing of languages like PHP, Python, and Ruby, each vying for attention. Java stands out in enterprise application development, with its ecosystem led by Spring attracting countless programmers. As the bottleneck for web programming is no longer the CPU, but rather I/O, Java has also made breakthroughs in some server-side software, surpassing C/C++. In the field of big data, Java leads the way in data collection, storage, and computation, while languages like Python excel in data analysis. Go language has surprisingly penetrated the realms of cloud computing and backend programming, with limitless potential. Overall, I believe there are two key points to note: 1. Each language has its own characteristics and applicable scope; there is no absolute hierarchy. 2. Application layer programming changes rapidly (especially with JS), while lower-level programming changes relatively little.
