One. Go language is concurrent born
As mentioned above, hardware manufacturers are adding more and more cores to processors to improve performance. All data centers are run on these processors, more importantly, today's applications use multiple micro-services to maintain the database connection, message queues, and Maintenance Cache. Therefore, the development of software and programming language should be able to easily support concurrency, and should be able to with the increase in the number of cores of the CPU can be extended.
However, most modern programming languages (such as Java, Python, etc.) are from single-threaded environment in the 1990s. While some framework programming language to master after a multicore continue to improve the efficiency of resource use, such as the Java Netty, etc., but still requires developers to spend a lot of time and effort to get to know the operational principles of these frameworks.
Go released in 2009, when multi-core processors already on the market. Go native language has design advantages on multicore concurrency, Go language from the ground up to support concurrent native, without third-party libraries, developers programming skills and development experience.
Many companies, especially the Chinese Internet company, is about to or have already finished with the process of the transformation of the old system Go language. Go through the language system can be reconstructed using less hardware resources to achieve higher concurrency and I / O throughput performance. Fully tap the potential of the hardware equipment is also refined to meet the current market environment operations.
Go concurrent language is based on the goroutine, goroutine similar thread, but not threads. goroutine it can be understood as a kind of virtual threads. Go language runtime scheduling goroutine be involved, and goroutine reasonably allocated to each CPU, maximizing the use of CPU performance. Open a goroutine consumption is very small (about 2KB of memory), you can easily create millions goroutine.
goroutine features:
- goroutine having increased stack segment. This means that they will use more memory only when needed.
- goroutine startup time is faster than thread.
- goroutine native support for using the channel to communicate securely.
- goroutine shared without the use of mutex data structure.
GO advantages:
( 1 ) support cross-compilation , compiling fast
( 2 ) the development of high efficiency
( 3 Good) execution performance
( 3 ) naturally supports concurrent
two. Go powerful performance
And other modern high-level languages (such as compared to Java / Python), using C, C ++ is the biggest advantage of their performance. Because the C / C ++ is a compiled language rather than interpreted language. The processor can only be understood binaries, Java and Python when running such a high-level language needs first human-readable code is translated into byte code, and then reconverted to binary processor can be understood by a dedicated interpreter.
GO features:
Simple and easy to learn
Development of high efficiency
Good execution performance
three. Go language is easy to learn
1. The syntax is simple
Go language is easy to learn, learning curve is gentle, not like the C / C ++ language easily take two to three years of study period. Go language is called "C language Internet age." Go language style is similar to the C language. Syntax in the C language based on a substantial simplification, remove unwanted expression in parentheses, the cycle only for a representation method, traversal can be achieved various values, key value and the like.
2. Uniform Code style
Go language provides a set of formatting tools fmt - Go . Some Go language development environment or editor when you save will be formatted using the formatting tools to modify the code, thus ensuring the code is different developers to submit a unified format. (Tucao: no longer have to worry about those who do not understand the black magic ...)
3. Development of high efficiency
Go development language to achieve the perfect combination of efficiency and execution efficiency, allows you to write C code (performance) like to write Python code (efficiency) the same.
four. Learning Go Language prospects
Currently Go Wide-language has been used in the Pan artificial intelligence, cloud computing development, container virtualization, zoomed data development, data analysis and scientific computing, the development of operation and maintenance, reptiles field development, game development.
Go language is easy to learn, naturally supports concurrent perfectly fit the current highly concurrent Internet ecosystem. Go language job demand continues to climb, the current small number of programmers Go, good treatment.
Seize the trend, to learn to be a leader rather than a follower.
Domestic huge demand potential in Go, present, whether domestic manufacturers and emerging Internet companies are basically there will be job requirements Go language.
Why you should learn GO language?
