esid: sec-%typedarray%.prototype.indexof
description: Returns -1 if length is 0
info: |
22.2.3.13 %TypedArray%.prototype.indexOf (searchElement [ , fromIndex ] )
%TypedArray%.prototype.indexOf is a distinct function that implements the same
algorithm as Array.prototype.indexOf as defined in 22.1.3.12 except that the
this object's [[ArrayLength]] internal slot is accessed in place of performing
a [[Get]] of "length".
22.1.3.12 Array.prototype.indexOf ( searchElement [ , fromIndex ] )
...
2. Let len be ? ToLength(? Get(O, "length")).
3. If len is 0, return -1.
