Simple analysis of the difference between new and make in Golang

This is a created article in which the information may have evolved or changed.

So people can, was convinced that can.

The person can therefore, is convinced can.

New () can assign content to a reference type, but not a full creation. In map, for example, only the memory required for the type itself (wrapping the type's pointer) is allocated. There is no allocation of the memory required by the key value, nor does it initialize the internal properties such as the hash bucket, so the case is panic.

func main(){    a：= new(map[int]int)    b := *a    b[1] =  1 // 此处panic了信吗？！}
