SharedArrayBuffer.prototype.slice()
 The SharedArrayBuffer.prototype.slice() method returns a new SharedArrayBuffer whose contents are a copy of this SharedArrayBuffer's bytes from begin, inclusive, up to end, exclusive. If either begin or end is negative, it refers to an index from the end of the array, as opposed to from the beginning. This method has the same algorithm as Array.prototype.slice(). 
Try it
Syntax
slice()
slice(begin)
slice(begin, end)
Parameters
 
begin Optional
  Zero-based index at which to begin extraction.  A negative index can be used, indicating an offset from the end of the sequence. slice(-2) extracts the last two elements in the sequence.   If begin is undefined, slice begins from index 0.   
end Optional
   Zero-based index before which to end extraction. slice extracts up to but not including end.   For example, slice(1,4) extracts the second element through the fourth element (elements indexed 1, 2, and 3).   A negative index can be used, indicating an offset from the end of the sequence. slice(2,-1) extracts the third element through the second-to-last element in the sequence.   If end is omitted, slice extracts through the end of the sequence (sab.byteLength).   Return value
A new SharedArrayBuffer containing the extracted elements.Examples
Using slice()
const sab = new SharedArrayBuffer(1024);
sab.slice();    // SharedArrayBuffer { byteLength: 1024 }
sab.slice(2);   // SharedArrayBuffer { byteLength: 1022 }
sab.slice(-2);  // SharedArrayBuffer { byteLength: 2 }
sab.slice(0, 1); // SharedArrayBuffer { byteLength: 1 }
