Example in README doesn't work

[blinry]

Hey :)

When we tried to run the provided example in the README (in TypeScript), we encountered three issues:

• Overwriting "nvim.window" gave us a type error. We solved this by just assigning to a local variable.
• Using the provided tests, the check that lines should be [""] failed for us. It actually was equal to [].
• We got the error "nvim_proc.disconnect() is not a function". Not sure yet why.

Can you reproduce these errors?
