I recently learned about the hashbang syntax for writing comments in JavaScript, and need to know if it is or has the potential to be any different then just putting a // at the top of a file. Are there any conventions associated with the hashbang?
I am referring to usage in a browser environment only, not in a shell or NodeJS, etc.
I am asking because I am writing about JavaScript syntax and need to make sure it is 100% correct.
>Solution :
Hashbang has no meaning to JavaScript, as far as it’s concerned it’s just a comment. The only reason it exists is because Unix treats files beginning with #! specially when you try to run them as commands, and this can be used to run node.js automatically on a server.
This is meaningless in a browser, which loads scripts explicitly. So The hashbang has no special function on the client.
