This article is to share with you about the comparison between Go and other programming languages. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

Anyone who has worked in the software industry for a period of time knows that there is no universal programming language, no universal development framework, let alone no universal solution. The emergence of any new technology should be attributed to the strong dissatisfaction of some people with old technology. The Go language is no exception. For example, the dependency management of C language, C++ garbage collection, Java's clunky type system and heavy Java EE specification, and the performance of scripting languages such as PHP, Python and Ruby are all issues that many developer communities often debate and complain about.

Advantages of Go language

Go language is the master of multi-programming paradigm, which embodies the excellent ideas and principles of software engineering. Its characteristics enable developers to develop, test and deploy programs quickly, which greatly improves the production efficiency. Let's take a look at the advantages of the Go language over other mainstream languages.

1) Go language has clear dependency management and automatic garbage collection mechanism, so the amount of code is greatly reduced and the development efficiency is greatly improved.

2) compared with Java, Go language has concise type system, functional programming paradigm and advanced concurrent programming model. Therefore, the code block is smaller, more concise, more reusable, and can run faster in a multi-core computing environment.

3) for PHP, Go language is more universal and normative. This makes it more suitable for building large-scale software and better organizing modules together. In terms of performance, PHP is not the same as Go.

4) for Python/Ruby, the advantage of Go lies in its concise syntax, non-invasive and flat type system, and natural multi-paradigm programming model. Like PHP, Python and Ruby are dynamically typed interpreted languages, which means that they run much slower than statically typed compiled languages.

In a word, the biggest advantage of Go language for most mainstream languages is its high productivity, advanced dependency management and type system, and native concurrent computing support. Therefore, Go language has been concerned and favored by developers in various fields since it was released.

The disadvantages of Go language

Next, let's take an objective look at what the current Go language needs to be enhanced or improved (although some Gopher doesn't think so).

1) from a distributed computing perspective, the Go language is not as mature as Erlang (there are already some Go language code packages in this area, and we can see a bright future).

2) from the point of view of the running speed of the program, although Go is comparable to Java, it is not as good as C (the gap is constantly narrowing).

3) from the perspective of third-party libraries, the number of libraries in Go is far less than that of other mainstream languages (such as Java, Python, Ruby, etc.). However, compared with the age of the Go language, there are already quite a large number of third-party libraries implemented in it, and their number continues to grow rapidly.

In addition, at a deeper level, there are some unsatisfactory aspects of the Go language standard library, as follows.

1) from the perspective of language grammar, there is not much grammatical sugar in Go language grammar, which makes many Python and Ruby enthusiasts disdain it. In addition, there are a lot of ways to assign variables. What is most regrettable and what I care about is that the Go language does not support custom generic types.

2) from a concurrent programming perspective, the concurrency model provided by the Go language is powerful, but there are some writing rules that need to be understood. Otherwise, it is easy to step into the "pit". In fact, it is not recommended to call this a "pit". Because most of these so-called "pits" are dug out by ourselves because we are not familiar with the principles.

3) from the point of view of garbage collection, Go language garbage collection uses a concurrent tag removal algorithm (Concurrent Mark and Sweep,CMS). Although it is a concurrent operation that takes much less time than a serial operation, it still stops all user programs during garbage collection. This will more or less affect the applications with high real-time requirements. However, this problem has been greatly improved in versions of the go language since 1.3.

Although the Go language has some flaws, on the whole, it is already a very good general-purpose programming language. Moreover, the future development of the Go language will focus on performance, reliability, portability and some feature enhancements, so the above shortcomings will gradually weaken and disappear with the advance of the version.

This is how the Go language compares with other programming languages. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
