Older techs remember when it was only browser-based and they thought of, and perhaps still think of, "scripting languages" as something that would run from some command-line or another. Starting a GUI browser to run a mere script was a ridiculous concept. (There was also that JavaScript had no filesystem access. At least initially. And then it became a gaping security hole, but I digress.)
Today, there exist command-line accessible versions of JavaScript but even there (I figure) most people wince and choose anything else instead. Maybe even Perl.
But another definition of "scripting language" is "(any) interpreted programming language" and where it runs is unimportant.
From that perspective, sure, JavaScript qualifies. And so does QBASIC.
