Not that it's such a great language - it has strengths and weaknesses - but
this is more a problem of understanding how the language and the implementation relate to each other.

JS is typically used as a scripting environment embedded in some other application. The 'parent' application might be written in C or Java for example. The parent application might be a BBS, a print accounting system, an authentication provider, the firmware on a radio, a web browser, or a development platform like node.js. (These are places where I've used JS.)

Sometimes the parent application uses JS sparingly, eg. some event happens, and a script is executed to do a few custom things. Sometimes the entire point of the parent application is to run your JS and let it access system resources (files, network, etc.) It all depends.

You absolutely want to make certain things up as you go along, if you're embedding a JS engine in your product. There are things you'll want scripts to be able to do which have no rightful place in the language's core. This can be done well and it can be done poorly, but it's not inherently wrong.
