The go language is not entirely Chinese. It is a statically strongly typed, compiled language developed by Google's Robert Griesemer, Rob Pike and Ken Thompson.
Go language is born for concurrency
GO language is an open source programming language developed by Google. It was born in January 2006, open sourced in November 2009, and released in 2012 stable version. The Go language has native design advantages in multi-core concurrency. The Go language natively supports concurrency from the bottom up, without the need for third-party libraries, developers' programming skills and development experience.
Go is a very young language. 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"
Systems restructured with the Go language can use fewer hardware resources to achieve higher concurrency and I/O throughput performance.
The concurrency of Go language is based on goroutine. Goroutine is similar to a thread, but not a thread. Goroutine can be understood as a virtual thread. The Go language runtime will participate in scheduling goroutine and reasonably allocate goroutine to each CPU to maximize the use of CPU performance.
Characteristics of goroutine:
Have a growable segmented stack. This means they only use more memory when needed
Faster startup times than threads
Native support for communicating securely using channels
No need when sharing data structures Using mutex locks
Easy to learn
Simple language
The style of Go language is similar to C language. Its syntax has been greatly simplified based on the C language, and unnecessary expression brackets have been removed. The loop only has one expression method, for, which can realize various traversals such as numerical values and key values.
Unified code style
Go language provides a set of formatting tools-go fmt. Some Go language development environments or editors will use formatting tools to modify the format of the code when saving, thus ensuring that the code submitted by different developers is in a unified format.
High development efficiency
Go language achieves the perfect combination of development efficiency and execution efficiency, allowing you to write C code (performance) just like writing Python code (efficiency)
Suitable for what
Server-side development
Distributed systems, microservices
Network programming
Blockchain development
Memory KV database, such as boltDB, levelDB
Cloud platform
Prospects
Currently, Go language has been widely used in cloud computing development, Blockchain development, container virtualization, big data development, data analysis and scientific computing, operation and maintenance development, crawler development, game development and other fields.
The Go language is easy to learn, inherently supports concurrency, and perfectly fits the current high-concurrency Internet ecosystem. The demand for jobs in the Go language continues to rise. The current number of Go programmers is small and the salary is good.
