esid: sec-%typedarray%.prototype.findindex
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 ] )
...
6. Repeat, while k < len
...
b. Let kValue be ? Get(O, Pk).
c. Let testResult be ToBoolean(? Call(predicate, T, « kValue, k, O »)).
...
9.4.5.8 IntegerIndexedElementGet ( O, index )
...
3. Let buffer be the value of O's [[ViewedArrayBuffer]] internal slot.
4. If IsDetachedBuffer(buffer) is true, throw a TypeError exception.
