How to find the buffer number of a :terminal?

Question

I can see that I've got a terminal buffer open by running :ls R which finds all buffers with a running terminal job, but I don't know how to capture just the buffer number.

The closest I can get is echo bufnr("cmd.exe") because the buffer name has the command the terminal is using. This isn't crossplatform though.

bufnr("R") doesn't seem to search the flags the same was :ls R does.

By :h 'buftype'

echo filter(map(getbufinfo(), 'v:val.bufnr'), 'getbufvar(v:val, "&buftype") is# "terminal"')

By :h getwininfo()

 echo uniq(map(filter(getwininfo(), 'v:val.terminal'), 'v:val.bufnr'))

Thanks for these! Makes sense there isn't a builtin way to get a terminal buffer's number directly given how you can have so many – TankorSmash Jun 10 '20 at 00:02
Which one would be faster? just curious... – codepoet Jan 26 '21 at 11:07
