+description: Returns a string
+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 ] ] )
+  
+  ...
+  5. Let firstElement be ? Get(array, "0").
+  6. If firstElement is undefined or null, then
+    a. Let R be the empty String.
+  7. Else,
+    a. Let R be ? ToString(? Invoke(firstElement, "toLocaleString")).
+  8. Let k be 1.
+  9.Repeat, while k < len
+    a. Let S be a String value produced by concatenating R and separator.
+    b. Let nextElement be ? Get(array, ! ToString(k)).
+    c. If nextElement is undefined or null, then
+      i. Let R be the empty String.
+    d. Else,
+      i. Let R be ? ToString(? Invoke(nextElement, "toLocaleString")).
