Broadly speaking its a language that you can use to write scripts to
manipulate the web page inside your browser.

Eh? That sounds more like something you'd use CSS for.

Javascript has nothing to do with Java except for having a similar
sounding name.

Nothing to do with hardware, the language is interpreted by your
browser. For the most part, you might be using it to
create/remove/modify elements (such as tables, paragraphs, etc) that
make up the web page being displayed. What is displayed would then
change accordingly.
