JS Style Guide: Drop onevar as a requirement

[jzaefferer]

There are various reasons why onevar is bad, like always changing unrelated lines when adding or removing variables. jshint actually remove the onevar option recently. Instead of specifying how variables should be declared without onevar, I've removed the entire Assignments section. We can bring it back in the future when there is consensus, if its needed at all.

I'm good with this, it just makes onevar optional so we can continue to use it and still be in compliance with the style guide? That said, I've started to come around to the "one var per variable" because of the diff issue.

I highly support one var per variable, and keeping with the "all at the
top" if we are making changes to this section. I understand there is a lot
of code using the old way tho...

Yes, but ideally all of the jQuery projects (not all of the jQuery Foundation projects) have the exact same styles. There's an important distinction there and I think consistency in the former is important. See also jquery/content#8.

@jzaefferer No objections in a month. I'd say this is safe to land :-)

[arthurvr]

Sure!

Merged. We can still add more specific var rules later, project-specific or generic.

We need a replacement for this and I think it should be for all projects. I'd like to be able to enforce some value for http://jscs.info/rule/requireMultipleVarDecl.html or http://jscs.info/rule/disallowMultipleVarDecl.html and that should probably be included in the jquery preset.
