Javascript or Javascript script?

What is the right name for a pice of javascript?

Sartre once said "Hell is other people" .

Obviously he did not use public transportation very often.

The more you learn languages like Javascript and Python, the more you realise that while every syntax differs, they're all essentially themes of the same if, else or and, type statements... This leads me to believe that with enough practice, it's possible to shortcut or pick up a new language progressively faster. Or am I just a melon?
