Recently i saw an open source javascript library have a line like :
"style style.css"
var x=0
var ver=1
What is the significance of the style directive like above inside a javascript file? Is it some kind of directive for an editor or something ?
From the javascript point of view the semantic of the first line is more or less NOP.
It’s just an expression to be trivially evaluated.
This trick is used for example for declaration of javascript Strict mode.
In your example, it seems to be used to put some metadata into the script.
It’s very handy method for it’s backward compatibility with older javascript engines (no extra syntax).
