Better console.log
["log", "warn"].forEach(function(method) {
var old = console[method];
console[method] = function() {
var stack = (new Error()).stack.split(/\n/);
// Chrome includes a single "Error" line, FF doesn't.
if (stack[0].indexOf('Error') === 0) {
stack = stack.slice(1);
}
var args = [].slice.apply(arguments).concat([stack[1].trim()]);
return old.apply(console, args);
};
});
