description: >
Predicate may detach the buffer
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".
...
22.1.3.9 Array.prototype.findIndex ( predicate[ , thisArg ] )
Repeat, while k < len,
Let Pk be ! ToString(F(k)).
Let kValue be ? Get(O, Pk).
Let testResult be ! ToBoolean(? Call(predicate, thisArg, « kValue, F(k), O »)).
...
IntegerIndexedElementGet ( O, index )
Let buffer be the value of O's [[ViewedArrayBuffer]] internal slot.
If IsDetachedBuffer(buffer) is true, return undefined.
