This rule aims to keep consistent formatting on a function call. A call to a function that spans multiple lines because of an array, object or anonymous function call should begin and end with the same indentation.
Invalid example:
_.map(languages,
function(lang) {
return lang.name;
});
The inner function should have started on the same line as the outer and the inner function's closing bracket should be indented to the same level as the line of the outer function.
Valid example:
_.map(languages, function(lang) {
return lang.name;
});
