Aug 29, 2013 · Essentially, slices are a reference type "value" which contain fields for a pointer to the backing array, len, and cap -- the function you're appending in is modifying the backing array and the local copy of that slice header, but the main function's copy of the slice header remains unmodified. Arrays, slices (and strings): The mechanics of 'append'. Every array could be a slice but not every slice could be an array. If you have a fixed collection size you can get a minor performance improvement from using an array. At the very least you'll save the space occupied by the slice header.

Nov 24, 2009 · Slices. A slice is a reference to a section of an array. In memory, it is a 3-word structure contaning a pointer to the first element, the length of the slice, and the capacity. The length is the upper bound for indexing operations like x[i] while the capacity is the upper bound for slice operations like x[i:j].
