Does not exit after translation

[CsatiZoltan]

Trying your example with the Chromium-based Brave browser

./translate.js -p /usr/bin/brave-browser -t zh -s deepl 'stay the fuck home'

gives me the translated sentence

(node:7097) ExperimentalWarning: The fs.promises API is experimental
呆在家里

but does not exit. Why does it happen and how can I make it exit without closing the terminal and hence killing the process?
