Hello @kartik,

To print stacktrace of Error in console in more readable way:

console.log(ex, ex.stack.split("\n"));

Example result:

[Error] [ 'Error',
  '    at repl:1:7',
  '    at REPLServer.self.eval (repl.js:110:21)',
  '    at Interface.<anonymous> (repl.js:239:12)',
  '    at Interface.EventEmitter.emit (events.js:95:17)',
  '    at Interface._onLine (readline.js:202:10)',
  '    at Interface._line (readline.js:531:8)',
  '    at Interface._ttyWrite (readline.js:760:14)',
  '    at ReadStream.onkeypress (readline.js:99:10)',
  '    at ReadStream.EventEmitter.emit (events.js:98:17)',
  '    at emitKey (readline.js:1095:12)' ]

Hope it helps!!

Thank you!!
