Learn JS - Free Interactive JavaScript Tutorial

The third tutorial "Manipulating Arrays" is broken. myQueue.unshift(); prints 3, no matter what variable is inserted prior.

input:

  var myQueue = [];
  myQueue.push(1);
  myQueue.push(2);
  myQueue.push(3);

  console.log(myQueue.unshift());
  console.log(myQueue.unshift());
  console.log(myQueue.unshift());

output:

  3
  3
  3

Nice, is it just for basic js or tutorials like WebRTC/Filesystem api and such are welcome?

This has A LOT of potential. Good luck! By the way - looks so similar to http://www.learnpython.org/

This is very nice. I will recommend it to friends.

Useful!
