Hello,
I want to find what is `res` at `docRes.set({}).then(res=>{});`. The one thing I know from the entire documentation*, the res would return updateTime. Only it.
So my question is, where can I find the complete documentation about `res`. What is the output of it? How can I used it? Could you give me the link to the documentation?
I know I can done it only with logging it. But It only show what data inside without knowing why the data inside. So... I would happy if I can found the complete reference about the `res`?
I only seeing this docs and ofcourse I read another api too.
