Is golang a high-level language?

Golang is a high-level language. It is programming that is closer to natural language and mathematical formulas. It is basically separated from the hardware system of the machine and writes programs in a way that is easier for people to understand. It is used to solve practical problems in the development process of large systems. Designed to solve problems, it supports concurrency, unified specifications, simplicity and elegance, and powerful performance. Its main goal is to "have both the development speed of dynamic languages ​​such as Python and the performance and security of compiled languages ​​such as C/C."

go is a high-level language. Go language is a high-level programming language open sourced by Google in 2009. It is designed to solve practical problems in the development process of large-scale systems. It supports concurrency, unified specifications, simplicity, elegance, and powerful performance; its main goal is to "have both The development speed of dynamic languages ​​such as Python and the performance and security of compiled languages ​​such as C/C."

Computer languages ​​are divided into high-level languages ​​and low-level languages. High-level language is mainly relative to assembly language. It is programming that is closer to natural language and mathematical formulas. It is basically separated from the hardware system of the machine and writes programs in a way that is easier for people to understand. The program written is called the source program.

High-level language does not refer to a specific language, but includes many programming languages, such as the popular go language, java, c, c, C#, pascal, python, lisp, prolog, FoxPro , Easy Language, Chinese version of C language, etc. The syntax and command format of these languages ​​are different.

Go language is a high-level programming language open sourced by Google in 2009. It is designed to solve practical problems in the development process of large-scale systems. It supports concurrency, unified specifications, simplicity and elegance, and powerful performance. It is used by many Go language evangelists hail it as "the C language in the cloud computing era." The main goal of the Go language is to "have both the development speed of dynamic languages ​​such as Python and the performance and security of compiled languages ​​such as C/C."

The Go language is sometimes described as a "C-like language", or "the C language of the 21st century". Go inherits similar expression syntax, control flow structure, basic data types, call parameter value transfer, pointers and many other ideas from C language. It also has the running efficiency of compiled machine code that C language has always valued and is consistent with existing Seamless adaptation to the operating system.

Pros and Cons of Go Programmer’s Voice: If the real world requires me to prototype, test, and deploy a production system in a few days and handle 5 times more requests per second, The CPU and memory overhead are still very small. I think only the Go language can do it.

Go language has the following advantages:

Separate binary release: Go project compilation will generate a static executable file. This file can be run without any other dependencies. This approach is particularly suitable for cloud-native container environments.

Cross-compilation: Compile binaries on any operating system that run on other platforms. For example, on a Mac system, binary files can be compiled that can run on Linux and Windows. Garbage collection: Go language supports garbage collection. In comparison, C, Rust, etc. require developers to control themselves. Execution performance: Go is very fast. Performance is close to C. Much higher than Java, Python, and Node. Development efficiency: Go language has both the running performance of static languages ​​and the development efficiency of dynamic languages.

Simplicity and efficiency: The design philosophy of the Go language includes simplicity and efficiency. A typical counterexample is the complex and bloated Java language. Concurrency: The language level supports concurrency, simplifies concurrent development through coroutines and channels, and improves concurrency performance.

Rich standard library: The Go standard library covers text, IO, network, encryption, Web services, remote RPC, template engine and other functions. C language can be called: C language functions can be called to further optimize performance and reuse the huge ecosystem of C language.

Fast compilation time: Go compiles very quickly. You can refer to two static blog generation systems, Hexo (developed by Node) and Hugo (developed by Go).

Engineering type: The purpose of Go language design is to become an engineering language to solve actual engineering problems. The Go language defines development specifications and provides a wealth of tools. Using Go language, you can write programs that are easy to read and understand, and easy to test, maintain and expand.

Go language has the following shortcomings:

Lack of heavyweight framework. Such as Ruby's Rails, Python's Django, and Java's Spring.

Error handling: No exception system. Go officials are fixing this problem.

Software package management: For a long time, Go has not officially had a package management system. Until recently, Go version 1.13 officially introduced Go Module as an official dependency management tool.

is not a standard object-oriented programming model: this is also an innovation of the Go language. If you are a solid OOP adherent, this may be a bit uncomfortable.
