saving the hash key in a separate array

Question

saving the hash key in a separate array

Currently, I have a collection of key-value pairs that need to be stored in another array. However, I am facing difficulties with the logic as I am unable to keep track of which keys-values have already been assigned while iterating over the list of objects.

var kv={"a":2,"b":1,"c":1};
var list_of_objects=[bob,bill,jane,joe];//these are objects

The Objective

bob.kv="a"
bill.kv="a"
jane.kv="b"
joe.kv="c"

Additional Information: The property kv belongs to individual objects such as bob, bill, jane, or joe.

Answer №1

If you're looking for a solution, consider using the Object.keys() method.

Object.keys(kv).forEach(function(key) {
  var val = kv[key];
  while(val-- > 0) {
    var obj = objects.shift();
    obj.kv = key;
    console.log(obj)
  }
});

Similar to @MatUtter's response, this solution avoids modifying the original list_of_objects array:

let currentIndex = 0;
for (let property in keyValue) {
    if (keyValue.hasOwnProperty(property)) {
        let value = keyValue[property];
        while (value-- > 0) {
            list_of_objects[currentIndex].keyValue = property;
            currentIndex++;
        }
    }    
}
