JavaScript console prints assigned value of variable before it has been assigned?

Question

I\'m deeply confused by the behaviour of either JavaScript, or the Chrome console. Can someone help me understand?

Basically I have the following JavaScript code, no

Answer 1

that's because the copied_array is a reference, and console.log is executed asynchonously, so the content of the array is modifed before the first log prints it.

you may copy the array before printing

console.log([].concat(copied_array));
