What language is used to implement go?

Go is implemented in goroutine language. 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." "The Go language runtime will participate in scheduling goroutines and reasonably allocate goroutines to each CPU to maximize the use of CPU performance.

GO language is an open source programming language developed by Google. It was born in January 2006, open sourced in November 2009, and released a stable version in 2012. 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 goroutines and reasonably allocate goroutines 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 leveraging channels safely Communication

• No need to use mutex locks when sharing data structures

Easy to learn

Concise 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 to do:

Server-side development

Distributed systems, microservices

Network programming

Blockchain development

Memory KV database, such as boltDB, levelDB

Cloud platform

Prospects:

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.
