Not being able to see your code as a whole can also cause much harder to spot subtle bugs as well. Still not worth the trade off.
Besides, you're forgetting this[^].

It's 2014, who cares how long the code file is. It's easier to read with the extra {}, it's easier to maintain with the extra {}. The only downside is typing extra {}. Don't you get paid per line anyway??

I care. Being able to see more at a glance is nice. It's also less convoluted when it's a simple statement. And I don't get paid per line, nobody does. I get paid to deliver a product that's useful. Nobody cares about line count except other nerds / devs.

Who cares how long the files are? They aren't being printed on paper (hopefully), and scrolling is not so hard.
Setting a trap for junior programmers that introduces a bug is not responsible programming. If you do that, you are responsible for the bug, not the newbie, and you should be "given a hard time" for compromising the code base just to be a jerk.

The trap isn't that hard to spot though. Seriously man, we're not talking about something difficult. It's just a peeve. We can debate, but that's all it is. Just a peeve. And my preference is that I'd rather see more of the file, because it's not that hard to spot.

I am currently working on a system where most of the software was written in C in the early 1980s. It is formatted so badly that stuff like
if (condition)
DoThis();
else DoThat();
DoAnotherThing();
is not uncommon at all. Add to that, there is no consistent use of tabs vs. spaces, no consistent tab stops, no naming conventions.
Honestly, use the braces or don't, just be consistent, dammit. Proper indentation is far more valuable than brace usage; don't use TAB for indentation, and do stuff the same way, every damn time.

it certainly is harder to maintain.
i can't count how many times i've had to fix something in code that only uses brackets when one or more statements are being controlled. so you get stuff like:
for (i=0;i<10;i++)
for (x=0;x<10;x++)
if (xyz) foo()
else for (z=0;z<10;z++)
bazinga();
bar();
and then you have to spend precious brain wattage figuring out that bar(); has nothing to do with any of the rest of it.
this isn't 1967, 3 bytes for a bracket and an CR/NL isn't going to run you out of punch cards. make the code readable!

The rule that I have is that you omit the braces iff the statement is a simple single line. Also, if either branch needs braces then both get them, and loops always have braces.
|
|

|

but that's the start of the problem!
someday, someone is going to have to come along and add some more logic in that if, and you've just forced them to do the work you should've done the first time!

I understand your point of view, but still prefer my way of doing things. What I find more troubling is that after working on a bunch of javascript, I'm starting to prefer the old school C style brace layout.
|
|
|
|

Correct.
If you have a 'rule' which says, "(don't) use braces, except in these special cases", then you have to remember the special cases.
I'm in the braces-good camp for the reasons Chris supplied above. Missing them doesn't make your code noticeably more concise, and does make your code (and, more importantly, your intentions, when you've run away from this project and I'm trying to figure it out [or vice-versa]) noticeably more readable.

You beat me to it man. If it's hard to read then I use them. For simple things concise wins. +5

I have to {
disagree.
}
I prefer the verbosity and clarity that the braces bring to the code.
Jeremy Falcon wrote: Concise wins, unless it's hard to read.
Which is usually what happens. People that use the latter form also tend to be the ones that crush every line together so that you first have to separate to properly understand. Is there a lack of space on your screen?
In any case a method bigger than a screen is just plain fugly.

I both agree and disagree. My personal coding style is:
if (expr) {
doSomething();
}
else {
doAnotherThing();
}
I like using the braces so that adding an extra bit of logic to the execution block won't inadvertently change the program flow, and at the same time placing the opening brace on the same line as the if... and the else statements compacts the code a bit. To me the advantage with compact code is that you can see more of the program logic in a single screen which means less time scrolling up and down trying to follow the program logic. For that reason, I'm ruthless in eliminating blank line whitespace except to visually offset functions or methods.

As much as I'm not a fan of that (even in JavaScript), that makes more sense than:
if (expr)
{
doSomethingForOneLine();
}
else
{
doAnotherThingForOneLine();
}You're version is at least concise, and no matter what some may say on CP, concise is important. Less is more. Always will be.

I personally prefer this convention:
if ((a cond b) conjunction
(c cond d) conjunction // Additional conditions always on separate line
(e cond f)) { // Always include opening brace
do .... something
} // Always closing brace
Or
} else { // Always closing brace..else..opening brace
do .... something else
} // Always closing brace
The same conventions and principles apply to loops (for, while, etc.) and other conditionals.
I strictly avoid NOT using braces under any circumstances.
I want to be able to see a complete thought, i.e., a block of code, in one intact, obvious section.
These are my thoughts based on years of chasing bugs, modifying other people's code, and having to debug somebody else's problem. Other people are welcome to use their own conventions, but I may not be able to help them efficiently.
Just because I can do something doesn't mean I should do it.

It's interesting that the older the programmer the more concision becomes important.

If their functions are really long  they can see more of it on one screen that way.
