+description: Returns an empty string if called on an empty instance
+info: |
+  22.2.3.28 %TypedArray%.prototype.toLocaleString ([ reserved1 [ , reserved2 ] ])
+
+  %TypedArray%.prototype.toLocaleString is a distinct function that implements
+  the same algorithm as Array.prototype.toLocaleString as defined in 22.1.3.27
+  except that the this object's [[ArrayLength]] internal slot is accessed in
+  place of performing a [[Get]] of "length".
+
+  22.1.3.27 Array.prototype.toLocaleString ( [ reserved1 [ , reserved2 ] ] )
+
+  ...
+  4. If len is zero, return the empty String.
