Answer 1

I know you want to save some keystrokes. Me too. However, I usually log the variable name and values much like others here have already suggested.

console.log({a:a, b:b});

If you really prefer the format that you already illustrated, then you can do it like this:

function log(o) {
    var key;
    for (key in o) {
        console.log(key + ":", o[key]);
    }
}

var a = '1243';
var b = 'qwre';
log({
    a:a,
    b:b
});

Either way, you'd need to include the variable name in your logging request if you want to see it. Like Gareth said, seeing the variable names from inside the called function is not an option.
