Writing in arrays cause invalid result

[klemmm]

Hello.

Defining an array, then writing to it and using it causes invalid result. Here is a minimal example showing the behavior:

Original:
====================
var a = ["hello"];
a[0] = "bye";
console.log(a[0]);

====================

var a = ['hello'];
'hello' = 'bye';
console.log('hello');
