This article mainly explains "what are the reasons for the popularity of Go language". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what are the reasons for the popularity of Go language".
First of all, I'd like to talk about why PHP programmers choose to use Go.
The first reason is performance, of course. The performance of the PHP language is indeed an age-old problem. The performance here refers to the IO performance of PHP. PHP does not have a NIO like Java, nor a non-blocking callback like NodeJS. The IO performance of the cooperative program that comes with Go is obviously better than that of PHP.
The second reason should be the process model of PHP. PHP does not support threads by default, and each process can only handle one request at a time. However, the underlying layer of Go's co-program is still running in threads, so it can take advantage of the multi-threading of the operating system and the multi-core capability of CPU.
The third reason may be the life cycle of PHP programs. At the end of each request, PHP reclaims most of the resources, including initialized database connections or other reusable singleton objects. At the beginning of each request, you also need to re-do the work of establishing a connection, instantiating an object, and so on. Applications developed with Go are memory-resident programs that do not recycle all resources, such as connection pooling and object pooling. Even though some database PHP extensions support long connections, they are not as simple and intuitive as Go.
The emergence of Swoole solves the first and third problems and makes up for some of the disadvantages of PHP. But the second problem remains unsolved. And developers must also install Swoole extensions separately, which is not as easy to use as Go native support for protocols and HTTP Server. Maybe in the future Swoole will solve the process model of PHP and make PHP really the best language in the world.
In addition to PHP programmers, many C, C++, and Java programmers are starting to use Go.
For C or C++ programmers, the reason for choosing Go may be complex syntax, such as header files and macro definitions. It may also be due to security issues, such as memory allocation and recycling. On the other hand, Go's syntax is much simpler and supports GC, allowing programmers to focus on implementing new ideas without having to deal with and care about many problems that have nothing to do with programming. The learning curve is smooth and the user experience is better. In addition, if you want to implement the cooperative program in C and C++ programs, you may need to introduce a third-party library.
Finally, Java programmers choose Go language because of complex syntax, complex xml configuration, inconvenient introduction of cooperative programs, inconvenient use of threads, and so on.
Thank you for your reading. The above is the content of "what are the reasons for the popularity of Go language?" after the study of this article, I believe you have a deeper understanding of the reasons for the popularity of Go language, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
