I have a question about "console.log" in Javascript Web Office Addins. Currently I am working on Javascript Word Addin and can't troubleshoot it, because I don't understand where the "console.log" output is sent. On Microsoft site there are a lot of examples, that contain contain "console.log", but they never specify how to check these outputs.
So, the question is how can I see this "console.log" output. I am not using Visual Studio.

When you say you're not using Visual Studio, do you mean that you're not using the Visual Studio template? Or that you physically don't have Visual Studio on the machine (if so, might I recommend you install it -- even just the free/community edition)?
Once you have that:
- Close all instances of Internet Explorer
- Go to Visual Studio -> Debug -> Attach to process
- Be sure to select "Attach to": "Script code"
- Select all the iexplore.exe instances
- Click "Attach"
You should now get a full debugging experience, complete with console output ("JavaScript console" window; use the Quick Launch (ctrl-Q) to launch it if it doesn't display be default), DOM Explorer (again, use Quick Launch if you don't see it), and more.

There is an alt way if you don't have Visual Studio. There is a tool in windows name is 'F12 Chooser', you can find it at Windows\SysWOW64\F12\F12Chooser.exe
More info can be found at: https://github.com/OfficeDev/office-js-docs/blob/master/docs/testing/debug-add-ins-using-f12-developer-tools-on-windows-10.md
In Mac you can use Safari Web Inspector as it is explained here:

In Windows is possible to just attach a debugger to the add-in:

I don't know if this option is available on free versions of Visual Studio, but with licensed VS 2015 I solved with a simple window:
(after starting the project) Debug > Windows > JavaScript Console
