Why my code snaps off the browser window when ran in console?

Question

When I ran the code in browser console or in js fiddle, this code snaps off the browser. I don't understand why it does. Can some one show some light ?

var sample = [1, 2, 3, 4];

function arrDupli(sample) {
  var mysample = sample;
    for (var i = 0; i < sample.length; i++) {
      mysample.push(sample[i]);
   }
  console.log(mysample);
}

arrDupli(sample);

"Snap off"? Do you mean it hangs because of the infinite loop? — Bergi, Sep 08 '16 at 18:08

you are creating an infinite loop, mysample and sample have both the same value, so you are basically just pushing the same value over and over.

Try creating and empty array instead var mysample = [];
