Reset the values ​of an assosiative array

I have an associative array with the following format: 

var array = [{"id": "28", "name": "Josh"}, {"id": "17", "name": "Karl"}];

Is there any way to empty the key values ​​of each array index?

I've done it this way, but I don't know if it's the best:

array.forEach(item => {

  item.id = "";
  item.name = "";

})

The way you're doing it is fine if you really want to have blank strings as the id and name of all of the objects. A slightly more modern approach would use an ES2015+ for-of loop, and you can use a single statement to set both values if you like:

for (const item of array ) {
    item.id = item.name = "";
}

But again, your forEach loop is fine, and works in environments that have forEach but don't have for-of.
