因为这个特质使得分发 Go 程序变得更容易,你不用让你的用户去装虚拟机(像 jvm 那样)了 自动扩容技术是通过 Go 的运行时 runtime 实现的,Go runtime 还包含其他一些服务:内存分配、垃圾回收、并发支持、网络和内建类型与函数 Slices 有自增容量的特质,如果你能知道 append 的大致范围,初始化的时候给一个尽可能...

When we doubled the capacity of our slice in the previous section, we wrote a loop to copy the old data to the new slice. Go has a built-in function,copy, to make this easier. Its arguments are two slices, and it copies the data from the right-hand argument to the left-hand argu...
The code: slice-array.gomake() functionGolang provides a library function called make() for creating slices. Following is the signature:func make([]T, len, cap) []T The make() function takes a type, a length, and an optional capacity. It allocates an underlying array with size equal...
Welcome to the part 11 ofGolang tutorial series. In this tutorial, we will learn about Arrays and Slices in Go. Arrays An array is a collection of elements that belong to the same type. For example, the collection of integers 5, 8, 9, 79, 76 forms an array. Mixing values of differ...
We don't see arrays too often in Go code. Slices, though, are everywhere. They build on arrays to provide great power and convenience. The type specification for a slice is[]T, whereTis the type of the elements of the slice. Unlike an array type, a slice type hasno specified length...
