[Docs] missing Array docs page.

[zander]

If you go to https://github.com/nodejs/node-addon-api/blob/master/doc/object.md
you will see the sentence;

and extends Napi::Array

the 'array.md' is missing in the doc directory, though.

I can't find any docs on the normal arrays.

Hi @zander,
the right link is https://github.com/nodejs/node-addon-api/blob/master/doc/basic_types.md#array sorry for the mistake.
