Why are lists used infrequently in Go?

Question

I\'m new to Go, and quite excited about it. But, in all the languages I\'ve worked with extensively: Delphi, C#, C++, Python - Lists are very important because they can be dynam

It depends a lot on the number of elements in your lists,
 whether a true list or a slice will be more efficient
 when you need to do many deletions in the 'middle' of the list.

#1
The more elements, the less attractive a slice becomes. 

#2
When the ordering of the elements isn't important,
 it is most efficient to use a slice and
 deleting an element by replacing it by the last element in the slice and
 reslicing the slice to shrink the len by 1
 (as explained in the SliceTricks wiki)

So
use slice
1. If order of elements in list is Not important, and you need to delete, just
use List swap the element to delete with last element, & re-slice to (length-1)
2. when elements are more (whatever more means)

There are ways to mitigate the deletion problem --
e.g. the swap trick you mentioned or
just marking the elements as logically deleted.
But it's impossible to mitigate the problem of slowness of walking linked lists.

So
use slice
1. If you need speed in traversal
