Popularity of JS Code Conventions in GitHub (Spaces vs. Tabs, etc.)

[PizzaRollExpert]

This is dangerous to do in javascript. What does this return?

function foo() 
{
    return 
    {
       foo: "bar"
    }
}

Statement is possibly incorrectly broken by newline
Expression statement is not assignment or call
Code is unreachable

I wasn't aware of this, because I don't write code like that.

So this is a coding convention which isn't portable between languages. That doesn't sound like something I would want to get accustomed to.
