What is the fastest way to remove specifc elements from all sub arrays or an array in javascript

I have an array like this:

"output" : [
  {
    "zip":35004,
    "state":"AL",
    "City":"Acmar",
    "lat":33.584132,
    "lng":-86.51557
  },
  {
    "zip":35005,
    "state":"AL",
    "City":"Adamsville",
    "lat":33.588437,
    "lng":-86.959727
  }
]

Now how do I remove 'lat' and 'long' from all the sub-arrays. I want an output like this:

"output" : [
  {
    "zip":35004,
    "state":"AL",
    "City":"Acmar"            
  },
  {
    "zip":35005,
    "state":"AL",
    "City":"Adamsville"           
  }
]

What is the fastest possible way to do this?

I guess 

for (var i = 0; i < row.length; i++) {
     delete row[i].lat;
     delete row[i].long;
}

For is faster than forEach and using delete is obviously
