Does the object javascript syntax right or wrong ?

Question

Here it is:

var obj = {
    'city': 'ny',
}

I write a comma in the end after ny

but this could run in Chrome and Firefox, but not in IE6/7

So does this kind of syntax is right or wrong or recommended?

Answer 1

there should be not comma,if you have only one key and value.

If you are separating the Key & Value Pairs with comma then it is called as Object Literals.

var obj = {
    'city': 'ny'
}
