How to Obtain Stack Trace Information in JavaScript?

stacktrace() Function for JavaScript Exceptions

Determining a JavaScript stack trace is accessible when JavaScript exceptions occur. However, acquiring a stack trace for custom exceptions thrown manually may require specific techniques.

For custom exceptions, the following script can be employed:

function stacktrace() { 
  function st2(f) {
    return !f ? [] : 
        st2(f.caller).concat([f.toString().split('(')[0].substring(9) + '(' + f.arguments.join(',') + ')']);
  }
  return st2(arguments.callee.caller);
}

Additionally, modern browsers offer the console.trace() function for capturing stack traces during debugging.

Updated Solution (2013):

A simpler approach is to utilize the Error object's stack property:

function stackTrace() {
    var err = new Error();
    return err.stack;
}
