description: >
[[Get]] of "length" uses [[ArrayLength]]
info: |
22.2.3.11 %TypedArray%.prototype.findIndex ( predicate [ , thisArg ] )
%TypedArray%.prototype.findIndex is a distinct function that implements the
same algorithm as Array.prototype.findIndex as defined in 22.1.3.9 except that
the this object's [[ArrayLength]] internal slot is accessed in place of
performing a [[Get]] of "length".
