!! Bang Bang Operator

There is no such operator, you are merely using the logical not operator (!) twice. Describing it as a single operator merely serves to create misunderstanding as to what is actually going on.

Officially, if we only refer to MDN docs, you are right. Its not a new operator. Its just a double NOT operator. But not everyone knows that we can do this, hence i include it here 😀

Regarding the name "Bang", as @webjose refer to western movies, here is the truth:

In the 1950s, secretarial dictation and typesetting manuals in America referred to the mark as "bang", perhaps from comic books – where the ! appeared in dialogue bubbles to represent a gun being fired – although the nickname probably emerged from letterpress printing. This "bang" usage is behind the names of the interrobang, an unconventional typographic character, and a shebang, a feature of Unix computer systems. In hacker culture, the exclamation mark is called "bang", "shriek"
