  an existing slice.
- [Sorted](/pkg/slices#Sorted) collects values from an iterator into a
  new slice, and then sorts the slice.
- [SortedFunc](/pkg/slices#SortedFunc) is like `Sorted` but with a
  comparison function.
- [SortedStableFunc](/pkg/slices#SortedStableFunc) is like `SortFunc`
  but uses a stable sort algorithm.
- [Chunk](/pkg/slices#Chunk) returns an iterator over consecutive
  sub-slices of up to n elements of a slice.

## WebSockets client

### In production

In your production system, you probably have a frontend created with a modern framework like React, Vue.js or Angular.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.
