esid: sec-%typedarray%.prototype.reverse
description: Get "length" uses internal ArrayLength
info: |
22.2.3.22 %TypedArray%.prototype.reverse ( )
%TypedArray%.prototype.reverse is a distinct function that implements the same
algorithm as Array.prototype.reverse as defined in 22.1.3.21 except that the
this object's [[ArrayLength]] internal slot is accessed in place of performing
a [[Get]] of "length".
22.1.3.21 Array.prototype.reverse ( )
1. Let O be ? ToObject(this value).
2. Let len be ? ToLength(? Get(O, "length")).
