Statically typed languages, but there is a feeling of a dynamic language, a statically typed language is a hidden majority of the problems that can be checked out at compile time, and the feeling of a dynamic language is that there are a lot of packages that can be used, and it is very efficient to write.
The language level supports concurrency, this is the biggest feature of GO, innate support for concurrency, I once said a sentence, there is a difference between natural genes and plastic surgery, everyone is equally beautiful, but do you like plastic surgery or the beauty of natural genes? go is the concurrency supported in the genes, which can make full use of multiple cores, and it is easy to use concurrency. Built-in runtime, support for garbage**, this is one of the features of a dynamic language, although the GC is not perfect at the moment, but it is enough to cope with most of the situations we can encounter, especially the GC in the future.
Easy to learn, the authors of the Go language have the gene of C, so Go naturally has the gene of C, then the Go keyword is 25, but the expressive ability is very strong, and it supports almost most of the features you have seen in other languages: inheritance, overload, objects, etc. Rich standard libraries, go has a large number of built-in libraries, especially the network library is very powerful, and I love this part the most.
Built-in powerful tools, there are a lot of built-in toolchains in the go language, the best should be the gofmt tool, automatic formatting, which can make team review so simple, the format is exactly the same, and it is difficult to think differently. Cross-platform compilation, if you write go** does not contain cgo, then you can do the window system to compile linux applications, how to do it? go cites the ** of plan9, which is the information that does not depend on the system.

Anonymous users2024-02-05The areas where the Go language is applicable are:
The Go language is mainly used for server-side development, and its positioning is to develop "large software", which is suitable for many programmers to develop large software together, and the development cycle is long, and the network service supports cloud computing.
As a server programming language, GO is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, databases, etc.; In terms of network programming, GO language is widely used in web applications, API applications, ** applications, etc.; In addition, the GO language can also be used in the field of in-memory database and cloud platform, and many foreign cloud platforms are currently developed using GO.
Go allows programmers to develop quickly, and it makes it easier for programmers to maintain and modify software as it grows. It combines the efficiency of traditional compiled languages with the ease of use and expressiveness of scripting languages.
As a large-scale project development language, GO language has been used by many large companies, and even completely turned to GO development, including Google, Facebook, Tencent, Alibaba, JD.com, Xiaomi, 360, Meituan, Didi and Sina, etc., so the development prospects of GO language are still very good!

Anonymous users2024-02-03The Go language is primarily used for server-side developmentIt is positioned to develop "large software", which is suitable for large software that requires many programmers to develop together and has a long development cycle and supports cloud computing network services.
The GO language combines the efficiency of traditional compiled languages with the ease of use and expressiveness of scripting languages, which not only improves the development speed of the project, but also makes it very easy to maintain in the later stage.
Compiler There are currently two GO compiler branches, the official compiler GC and GCCGO. The official compiler was initially written in C and later rewritten in go to bootstrap. GCCGO is a GO compiler that uses standard GCC as the backend.
The official compiler supports cross-platform compilation (but not CGOs), allowing the source to be compiled into binaries that can be executed on the target system and architecture.

It is also possible to declare the type without explicitly, type inference, but in a static language, the name can no longer be assigned a number when the string is placed at the beginning.
Methods, properties Separate The capitalization of the method's name is externally adjustable.
An important principle of object-oriented design: "Prioritize the use of composition over inheritance".
Dog is also an animal, and to reuse the attributes and methods of animal, you only need to write animal in the struct type
The entrance is also main, so try it with it.
Polymorphism, there is this method is the implementation of this interface, and the specific class does not need to know what interface it implements, using: Adding the keyword go before a function call starts a goroutine
Create a goroutine that will be added to a global running queueSchedulerwill assign them to someoneLogical processorsA logical processor is bound to oneOperating system threads, run the goroutine on it, if the goroutine needs to read and write a file, blocking, it will be out of the logical handler and directly goroutine-system thread binding.
Compiled to the same name. exe, not through the virtual machine, directly is machine code, the same as c, so very fast.
But there is also automatic garbage**, and each exe file already contains a runtime similar to a virtual machine for goroutine scheduling.
By default, it's statically linked, and that exe will add everything you need to run, so you can copy the exe anywhere to run, hence the generatedThe exe file is very large.
Be yourself.
The value and meaning of life is given by yourself, and what anyone else imposes on you is not your life, but someone else's life, so if you want to know what life is, only ask your own heart, where your heart goes, is the direction of your life, don't use other people's standards to demand yourself, otherwise you will always be a dancer on the stage, and spend a lifetime to interpret others, which is the biggest sorrow in life! >>>More
Our society is now in a period of rapid development. Peace and development are the main themes of our time. Peace is the foundation of development, and development is the guarantee of peace. >>>More
Put the child in a family environment where parents read and study every day, that is, he will be whipped every day and not let him read, and he will also read; On the other hand, if you put your child in a family environment where parents eat, drink, and quarrel every day, you will whip him every day and let him read, and he will not be able to read well.
The characteristic is that you can't straighten your tongue when you speak!
Computers have A and B languages, but they are only early versions of C and are not very useful, and Che is only used by early scientists, and most people don't know much about it.
