esid: sec-%typedarray%.prototype.join
description: Get "length" uses internal ArrayLength
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)
1. Let O be ? ToObject(this value).
2. Let len be ? ToLength(? Get(O, "length")).
...
5. If len is zero, return the empty String.
