When wrapping lines, the main objective is to improve readability. Feel free to break rules if it improves readability. Do not accept the auto-formatting suggested by the IDE as Eclipse’s JavaScript auto-formatting is very different from that suggested by TEAMMATES.

It is OK to exceed the limit slightly or wrap the lines much shorter than limit.

In general,

• Break after a comma.

// Bad
var alphabets = [
       a
   ,   b
   ,   c
];

// Good
var alphabets = [
   a,
   b,
   c
];

// Bad
var numbers = {
       one: 1
   ,   two: 2
   ,   three: 3
   ,   four: 4
};

// Good
var numbers = {
   one: 1,
   two: 2,
   three: 3,
   four: 4
};

• Align the new line with the beginning of the parent element.
  // Bad
  myFunction(arg1, arg2, arg3,
     nonAlignedArg4, arg5);

// Good
myFunction(arg1, arg2

           arg3, arg4);
myFunction(arg1,
          myOtherFunction(arg2,
                          arg3),
          arg4);

• Break before an operator. This also applies to other "operator-like" symbols like the dot separator (.).

// Bad
mySum = a + b + c +

        d;
myString = ‘Long line split’ +

           ‘split into two parts’;

$('#responses').
   find('.selected').
       highlight().
       end().
   find('.open').
       updateCount();

// Good

mySum = a + b + c

        + d;
myString = ‘Long line split’

           + ‘split into two parts’;
$('#responses')
   .find('.selected')
       .highlight()
       .end()
   .find('.open')
       .updateCount();

• Prefer higher-level breaks to lower-level breaks. In the example below, the first is preferred, since the break occurs outside the parenthesized expression, which is at a higher level.

// Bad
longName1 = longName2 * (longName3 + longName4

            - longName5) + 4 * longName6;

// Good

longName1 = longName2 * (longName3 + longName4 - longName5)

            + 4 * longName6;

• Here are three acceptable ways to format ternary expressions:

// Bad

alpha = (aLongBooleanExpression) ? beta

      : gamma;
alpha = (aLongBooleanExpression) ? beta

         : gamma;

alpha = (aLongBooleanExpression)

                            ? beta

                                     : gamma;

// Good

alpha = (aLongBooleanExpression) ? beta : gamma;
alpha = (aLongBooleanExpression) ? beta

                                 : gamma;

alpha = (aLongBooleanExpression)

      ? beta

      : gamma;
