console.trace()

The console interface's trace() method outputs a stack trace to the Web Console.

See Stack traces in the console documentation for details and examples.

console.trace( [...any, ...data ]);

...any, ...data Optional

Zero or more objects to be output to console along with the trace. These are assembled and formatted the same way they would be if passed to the console.log() method.

function foo() {
  function bar() {
    console.trace();
  }
  bar();
}

foo();

In the console, the following trace will be displayed:

bar
foo
<anonymous>
