>"Dang" is still a common word in English though

Dang is a common euphemism for the swear word damn, https://mashable.com/article/origin-of-swear-words - the euphemism "dang" was first used around 1780.

I believe it is also regional and somewhat archaic in use now unless you are real religious and probably also rural.
