Hi
Firefox 15 or later can use for-of statement.
I have a question about this.
var array = new Array(3);
for (var i in array) {
console.log(i);
}
for (var v of array){
console.log(v);
}
This for-in code logs nothing of course but for-of code logs 3 of undefined.
And also following code is same.
var array = [];
array.length = 3;
for (var i of array){
console.log(i);
}
for (var v of array){
console.log(v);
}
Are these behaviors correct ?
