foreach for JSON array , syntax

You can do something like

for(var k in result) {
   console.log(k, result[k]);
}

which loops over all the keys in the returned json and prints the values. However, if you have a nested structure, you will need to use

typeof result[k] === "object"

to determine if you have to loop over the nested objects. Most APIs I have used, the developers know the structure of what is being returned, so this is unnecessary. However, I suppose it's possible that this expectation is not good for all cases.

Try this:

$.each(result,function(index, value){
    console.log('My array has at position ' + index + ', this value: ' + value);
});

Sure, you can use JS's foreach.

for (var k in result) {
  something(result[k])
}
