Traverse through Javascript object properties

Question

I want to traverse through JavaScript object\'s property

    var obj =
    {
        a: \'value1\',
        b: \'value2\',
        c: \'value3\',
        d: \'va         


        

Answer 1

You should check that the property belongs to the object and not a prototype.

for (var prop in obj) {
    if (obj.hasOwnProperty(prop)) {
        obj[prop] = 'xxx';
    }
}
