Hi, I've looked through the tutorial on w3cschools.com, but I'm still
uncertain as to the difference between using break and using return.
If I have a simple "for" loop that I want to stop if a condition is
met, should I use break or return to stop the loop?
e.g. is something like this ok? Would using return do the same thing?
var dow = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday',
'Saturday', 'Sunday'];
var d = 'Wednesday';
for(var i = 0; i < dow.length; i++){
if (dow[i] == d){
var abc = dow[i];
break;
}
} 3 31435

simply put,
break exits a loop,
return exits a function.

That is too much simplified.
For the `break' statement may also occur outside of loops (i.e. `for',
for..in, do..while, and while..do statements followed by an execution
block), in the `switch' statement where it prevents execution from
considering the following `case' statements or the following `default'
statement within that `switch' statement.
Also, `break' does not return a value. `return', which exits the current
local execution context (the current function), does (if not explicitly
stated, it returns `undefined' from that context implicitly).

If someone could explain return true, and return false to me I'd

The c# *return* statement has been bothering me the past few months.
I don't like the fact that you can have different code paths in a method
and have multiple return statements. To me, it would be more orthogonal
if a method could only have one return statement.

Hi All,
At some places in code, I see following statements,

Is that any different from following syntax ?

Hello,
I was wondering, what's the difference between exit and return in the
main() function? For me they both look the same, or aren't they? And if
they aren't, which should I use in which situation?
Also I was wondering if it whould be wise to combine the standard
status with return.

I have an xml file that is read into an object using serialization. One
of the objects has a string field called delimeter that I want to
contain a carriage return. Instead of trying to include the carriage
return, I used "\r" thinking that when it was read back into the object
it would be interpreted as a carriage return. Instead, I am getting the
string literal instead of the escape sequence. Does anybody have a

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
