I have no idea what this does

? 30
: i.sign === 'D' ? 30 : 35,
marginRight:10 ,
width: this.props.pickupOrDropoff == "pickup"
? i.pickup
? 40

I love when the code is neat...
double zuida(std::vector<double> vec) {
std::vector<double> temp;
for(int i = 0; i < vec.size(); i++)
temp.push_back(vec[i]);
notend:
if(temp.size() > 0) {
if(temp.size() < 2) {
double tmp = *(&temp[0]);
return tmp;
}
else if(temp.size() >= 2) {
double mini = temp[0];
int ind = 0;
for(int i = 0; i < temp.size(); i++)
if(temp[i] < mini) {
mini = temp[i];
ind = i;
}
temp.erase(temp.begin() + ind);
goto notend;
}
}
}
The beauty is that every case is the best (also worst) case!

When you want your function always returns the correct value
class ExampleClass {
public void DoSomething()
{
if (this != null) {
//omitted
}
}
public void DoSomething2()
{
if (this != null) {
//omitted
}
}
}
Explanation: This can't be null in C# virtual instance methods - I was so confused by the widespread use of this check that I asked this question at SO: https://stackoverflow.com/questions/31747718/can-this-be-null-in-c-sharp-virtual-methods-what-happens-with-the-rest-of-ins
final int two_fifty_five_hex = 0xFF
final int two_fifty_five_dec = 255
One is in hex but the other is in decimal! Watch out, make sure you use the correct 255, not the other 255.

$desired_components[$name] = self::packPair(round($component_value, 2), $component_comments);
}
$('#userCheck').not(this).prop('checked', false);

At least [math] is used. So close, and yet so far...
