``` ```
Under the hood, make creates an unnamed array variable and returns a slice of it; the array is accessible only through the returned slice. In the first form, the slice is a view of the entire array. In the second, the slice is a view of only the array’s first len elements, but its capacity includes the entire array. The additional elements are set aside for future growth.
在底層，make創建了一個匿名的數組變量，然後返迴一個slice；隻有通過返迴的slice才能引用底層匿名的數組變量。在第一種語句中，slice是整個數組的view。在第二個語句中，slice隻引用了底層數組的前len個元素，但是容量將包含整個的數組。額外的元素是留給未來的增長用的。 在底層，make創建了一個匿名的數組變量，然後返迴一個slice；隻有通過返迴的slice才能引用底層匿名的數組變量。在第一種語句中，slice是整個數組的view。在第二個語句中，slice隻引用了底層數組的前len個元素，但是容量將包含整個的數組。額外的元素是留給未來的增長用的。
