esid: sec-%typedarray%.prototype.join
description: >
Concatenates the result of toString for each value with custom separator
info: >
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.
