Why this separate function is needed?

It would be better to handle/free the error if we happen to get one. I don't think hoping that people will play by the rules, and only pass valid arrays to this function is enough.

I don't think an intermediate variable is necessary.

If it is an array you can always retreive the length. It is an unconfigurable data property.

You can pass any 'const jerry_object_t *object_p' to this function

I am sorry I wasn't clear. So:
if array -> return length, always
if not -> return 0
So the correct comment is:
Returns 0, if the given parameter is not an array object

LGTM after these are fixed |
