Bad line breaking before '+', '-', '&&' etc, even when in parenthesis #735

function plusone(x) {
  return (x
    + 1);

In the function above JSHint complains that there is a Bad line breaking before '+', even though the whole return is within parenthesis, specifically to avoid ASI.

I use this style of coding because I find that it's easy to lose track of a + at the end of the line. Having it in the beginning gives me a better/quicker overview/understanding, especially when there is a really long, multi-line expression following.

Also operators which aren't subject to ASI are affected, such as && or ||. Is this considered bad style that should be avoided?

I am marking this as a bug but just letting you know this won't be very high on my priority list at the moment. As for && you are right, it is a style thing.

I like to have operators at the beginning of lines, be it + or && or other. As Skalman pointed out, it is too easy to lose track if they are at the end of a line.

There should be an option to disable this, at least (similar to what already exists for comma)

+1. I'm think prefix && and || can make code more readable:

var isValid = function() {
    return !this.position && !this.employer && !this.description
                && (angular.isDefined(this.position)
                    || angular.isDefined(this.employer)
                    || angular.isDefined(this.description));

Agree, just ran into this. I would love a "laxlogical" to except or/and rather than disable line break checking altogether.

I think the operator-first style is much easier to scan, especially for long multi-line conditionals, and there are no ASI gotchas in this case.


What's the state here? I think also operator-first style is much easier to read.

@martensms style-related rules are being deprecated and we recommend using JSCS which provides better style validation tooling. Ping @mikesherov if you have any questions about getting started.


mikesherov commented Sep 10, 2014

@rwaldron is this option still in the latest JSHint? I thought it was removed. If so, close this issue? If not, perhaps consider removing these rules.

@rwaldron So there's no option in jshint to deactivate that? Did you consider that this might be a break in usage? If style-related rules are deprecated, you should at least offer an option to deactivate it.

@martensms that happened before I took over the project.

@mikesherov I can't agree with you more.

+1 for && and ||
