Question

How would I loop through this correctly?

{names:['oscar','bill','brad'],ages:['20','25','18']}

So i’d basically get the output:

names: oscar
ages: 20

names: bill
ages: 25

names: brad
ages: 18

Yes I know its a for…in loop but I just can’t figure out how to get this output.

Answer 1

maybe

for (var i = 0, len = obj.names.length; i < len; ++i) {
  var name = obj.names[i];
  var age = obj.ages[i];
  // ... whatever
}

where “obj” is your JSON object
