The name was exclusively chosen based on marketing considerations, to have it benefit from the Java hype of the time. It was actually called LiveScript before.

but "JS" implies it is some sort of amalgam of the J and S programming languages - or it doesn't and probably the Java implication doesn't exist anymore either - who really, on hearing the name in a modern context is going to think "hey, it must be a scripting version of that one really old programming language granddad in the office is always reminiscing about"?

We can avoid your initials conflicting with anything by abbreviating your name to “JavaScript” now that is available.
