esid: sec-%typedarray%.prototype.join
description: Returns single separator if buffer is detached after ValidateTypedArray
info: |
%TypedArray%.prototype.join ( separator )
The interpretation and use of the arguments of %TypedArray%.prototype.join are the same as for Array.prototype.join as defined in 22.1.3.15.
When the join method is called with one argument separator, the following steps are taken:
Let O be the this value.
Perform ? ValidateTypedArray(O).
Let len be O.[[ArrayLength]].
If separator is undefined, let sep be the single-element String ",".
Else, let sep be ? ToString(separator).
Let R be the empty String.
Let k be 0.
Repeat, while k < len,
If k > 0, set R to the string-concatenation of R and sep.
Let element be ! Get(O, ! ToString(𝔽(k))).
If element is undefined or null, let next be the empty String; otherwise, let next be ! ToString(element).
Set R to the string-concatenation of R and next.
Set k to k + 1.
Return R.
