I understand the principles of asynchronous functions, but something is not clear to me: Scoping in asynchronous functions.
Example:
var path = "/my/folder/to/public/data";
http.createServer(function(request, response){
/* some malicious code is executed, however */
path = "/my/folder/to/private/data"
});
/* go on, go on, go on, wait here because of an synchronous function. */
/* while code execution is here, the callback-function of the server is called. */
fs.readFile(path+"myfile.txt", function(err, content){
console.log(content);
});
So, this is only an example. But how does it behave with the scopes/vars?
