What is the mascot of golang?

The mascot of the Go language is a gopher:

(The gopher has no name and is only called "Go gopher".)

Expansion:

The go language can currently reach 80% of the performance of c/c, which is much faster than the compilation speed of c/c. The currently popular open source software docker, kubernetes, lxd and other software are all written using the go language, and in 2016 In 2017, Go language was named the programming language of the year, which shows that the application scenarios of go are extraordinary.

Features of Go language Go language ensures that it can achieve the security and performance of a static compiled language, but also achieve the speed and ease of maintenance of dynamic language development. Some people describe the Go language: Go = C Python, explaining the Go language It not only has the running speed of C static language program, but also can achieve the rapid development of Python dynamic language.

Go language has the following features:

1. Automatic garbage collection

The most troublesome thing about C/C is the pointer problem. If you are not careful, the pointer will be wild or out of bounds. . In Go language, you no longer have to worry about delete or free, the system will automatically recycle it.

Wild pointer: Pointer to memory that has been released or memory that does not have access rights (illegal access). A wild pointer points to an uncertain address space, or it points to a certain address space, but the result of the reference space is unpredictable.

Unlike null pointers, wild pointers cannot be avoided by simply determining whether they are NULL, but can only be reduced by developing good programming habits. Operating on wild pointers can easily cause program errors.

2. Functions can return multiple values

This is amazing. Most languages ​​can only return one value, but Go language can return multiple values. This feature eliminates the need for developers to rack their brains to figure out how to return a value, and there is no need to define a structure specifically for passing values.

package main //Must import "fmt" func myfunc02() (a, b, c int) { a, b, c = 111, 222, 333 return} func main() { //Function call a, b, c := myfunc02() fmt.PRintf("a = %d, b = %d, c = %d\n", a, b, c)}

3 , Concurrent programming

The Go language is naturally concurrency. Only the keyword "go" is needed to execute functions concurrently, making concurrent programming simpler. This is also the biggest advantage of the Go language.
