esid: sec-%typedarray%.prototype.find
description: >
[[Get]] of "length" uses [[ArrayLength]]
info: |
22.2.3.10 %TypedArray%.prototype.find (predicate [ , thisArg ] )
%TypedArray%.prototype.find is a distinct function that implements the same
algorithm as Array.prototype.find as defined in 22.1.3.8 except that the this
object's [[ArrayLength]] internal slot is accessed in place of performing a
[[Get]] of "length". The implementation of the algorithm may be optimized with
the knowledge that the this value is an object that has a fixed length and
whose integer indexed properties are not sparse.
