Static/Dynamic vs Strong/Weak
...kly typed that "12" + "34" would equal "46", but "12" + "34Q" would equal "1234Q" [fortunately, one could write "12" & "34" if one wanted concatenation]. Curiously, variables holding numbers stored them as double-precision floats, and math on such variables used the floating-point values without...
Why does this (null || !TryParse) conditional result in “use of unassigned local variable”?
...l repro:
class Program
{
static bool M(out int x)
{
x = 123;
return true;
}
static int N(dynamic d)
{
int y;
if(d || M(out y))
y = 10;

}
}
I see no reason why that should be illegal; if you replace dynamic ...
Socket.IO Authentication

email: 'john@doe.com',

};
// we are sending the profile in the token
var token = jwt.sign(profile, jwtSecret, { expiresInMinutes: 60*5 });
res.json({token: token});
});
Now, your socket.io server can be configured as follows:

...s":"OK",
"reason":"some reason",
"content" :
{
"foo": 123,
"bar": "some value"
}
}
You'd then have a Content POJO:
class Content
{
public int foo;
public String bar;
}
Then you write a deserializer:

What is the parameter “next” used for in Express?
...) {
// check for and maybe do something with req.user
});
Since /users/123 will match the route in your example first, that will first check and find user 123; then /users can do something with the result of that.
Route middleware is a more flexible and powerful tool, though, in my opinion, sin...
