Go language slicing is an abstraction of arrays.

Go array length can not be changed, in a specific scene such a collection is not suitable, Go provides a flexible, powerful built-in type slice ("dynamic array"), the length of the slice is not fixed compared with the array, you can add elements, when appended may increase the capacity of the slice.

Define slicing

You can declare an array of unspecified sizes to define slices:

Var identifier [] type

The length of the slice does not need to be specified.

Or use the make () function to create a slice:

Var slice1 [] type = make ([] type, len) can also be abbreviated as slice1: = make ([] type, len)

You can also specify the capacity, where capacity is an optional parameter.

Make ([] T, length, capacity)

Where len is the length of the array and also the initial length of the slice.
