I would define a script as a program for automating tasks otherwise performed by a person. A scripting language such as Bash is primarily used to automate tasks which a user would otherwise manually perform on a shell. I would say that JavaScript is not a scripting language, nor did it begin as a scripting language, as its main use case has always been in providing interactivity to users, not in automating the tasks conventionally performed by users.
