+  22.2.3.15 %TypedArray%.prototype.join ( separator )
+
+  %TypedArray%.prototype.join is a distinct function that implements the same
+  algorithm as Array.prototype.join as defined in 22.1.3.13 except that the this
+  object's [[ArrayLength]] internal slot is accessed in place of performing a
+  [[Get]] of "length".
+
+  22.1.3.13 Array.prototype.join (separator)

+  ...
+  7. If element0 is undefined or null, let R be the empty String; otherwise, let
+  R be ? ToString(element0).
+  8. Let k be 1.
+  9. Repeat, while k < len
+    a. Let S be the String value produced by concatenating R and sep.
+    b. Let element be ? Get(O, ! ToString(k)).
+    c. If element is undefined or null, let next be the empty String; otherwise,
+    let next be ? ToString(element).
+    d. Let R be a String value produced by concatenating S and next.
