Go is a compiled and static typed programming language born from Google. Many of the core Go design and SDK development team members have many years of experience in the field of programming language research.
sliceare first-class citizens.
Go programmers are often called gophers.
In fact, although Go is a compiled and static typed programming language, Go also has many features which are usually only available in dynamic script languages. It is hard to combine these two kinds into one language, but Go did it. In other words, Go owns both the strictness of static languages and the flexibility of dynamic languages. I can't say there are not any compromises between the two, but the effect of the compromises is much weaker than the benefits of the combination in Go.
Readability is an important factor which affects the design of Go heavily. It is not hard for a gopher to understand the Go code written by other gophers.
Currently, the most popular Go compiler is written in Go and maintained by the Go design team.
Later we shall call it the standard Go compiler, or
(an abbreviation for Go compiler, not for garbage collection GC).
The Go design team also maintains a second Go compiler,
Nowadays it's use is less popular than
gc, but it always serves as a reference,
and both compilers are in active development.
As of now the Go team focuses on the improvement of
gc is provided in the official Go SDK.
Go SDK 1.0 was release at March, 2012.
The version of Go is consistent with the version of Go SDK.
There were/are two major versions released each year.
Since the release of Go 1.0, the syntax of Go has changed a little,
but there were/are many improvements for the tools in Go SDK, from version to version,
For example, noticeable lags caused by garbage collecting is a common
criticism for languages with automatic memory management.
But since Go 1.8, improvements made for the concurrent garbage collection implementation
gc basically eliminated the lag problem.
gc supports cross-platform compilation.
For example, we can build a Windows executable on a Linux OS, and vice versa.
Programs written in go language mostly compile very fast. Compilation time is an important factor for the happiness in development. Short build time is one reason why many programmers like programming with Go.
All the above advantages combined make Go become an outstanding language and a good choice for many kinds of projects. Currently, Go is popularly used in network, system tools, database development and block chain development areas. But there are also more and more game, big data and AI projects starting to use Go.
Finally, Go is not perfect in all aspects. There are certain trade-offs in Go design. And the current Go 1 really has some shortcomings. For example, Go doesn't support generics for custom types and functions now. Go team members are not against introducing custom generics into Go, they just haven't found a good solution yet which keeps Go clean and simple. Go 2 is in planning now. Nothing is impossible in the future.
