Javascript console.trace()
Where available it's also useful to know that the same stack trace is accessible as a property of the Error object. This can be useful for post-processing and gathering automated feedback.
function foo() {
console.trace('My log statement');
}
foo();
Output
My log statement VM696:1
foo @ VM696:1
(anonymous function) @ (program):1var e = new Error('foo');
console.log(e.stack);
