I'm really struggling with my code and cannot find a way to make it work.

I need to check whether my array exists or its length is not 0 and then if there is an object with a specific value in it. If so then update it. If not then add it. Please see my code below:

```
const originals = [];

if (!originals || originals.length === 0) {
  originals.push({
    "name": "Michael",
    "age": 21,
    "gender": "male"
  });
} else {
  for (i = 0; i < originals.length; i++) {
    if (originals[i].name !== "Michael") {
      originals.push({
        "name": "Michael",
        "age": 21,
        "gender": "male"
      });
    }
    if (originals[i].name == "Michael" && originals[i].age == 21) {
      originals[i].age = 22;
    }
  }
  console.log(originals);
}

```

Many thanks for your help in advance.

Reading between the lines what I think you want to do is:

* If "Michael" is in the array. Then his age should be updated to 21, if he is 22 years old.
* If "Michael" is not in the array. Then add Michael with an age of 21.

There are some odd things in your code which makes no sense to me. For example you are checking for "Michael" in the array each time when iterating the array. This would mean that you insert a "Michael" for each entry that is not named "Michael". That doesn't make sense, does it?

I think this is what you want:

```js
function addOrUpdateMichael(array) {
  const michael = array.find((x) => x.name == "Michael");
  if (!michael) {
      array.push({
          "name": "Michael",
          "age": 21,
          "gender": "male"
      });
  } else if (michael.age == 22) {
      michael.age = 21;
  }
  return array;
}

const testArray1 = [];
console.log(addOrUpdateMichael(testArray1));

const testArray2 = [{
    "name": "Michael",
    "age": 21,
    "gender": "male"
}, {
    "name": "Tony",
    "age": 18,
    "gender": "male"
}];
console.log(addOrUpdateMichael(testArray2));

const testArray3 = [{
    "name": "Michael",
    "age": 22,
    "gender": "male"
}, {
    "name": "Bob",
    "age": 36,
    "gender": "male"
}];
console.log(addOrUpdateMichael(testArray3));
```
The simple solution is below with help of amazing supporters on StackOverflow. Thank you all

```js
const originals = [{
    "name": "Michael",
    "age": 21,
    "gender": "male"
}];
if (!originals || originals.length === 0) {
    originals.push({
        "name": "Michael",
        "age": 21,
        "gender": "male"
    });
} else {
    for (i = 0; i < originals.length; i++) {
        if (originals[i].name !== "Michaels") {
            originals.push({
                "name": "Michaels",
                "age": 22,
                "gender": "male"
            });
        }
        if (originals[i].name == "Michael" && originals[i].age == 21) {
            originals[i].age = 24;
        }
    }
}
console.log(originals);
```
