Benchmark: angular.copy vs JSON.parse(JSON.stringify()) vs structuredClone AP_Object.assign(origArr)

angular.copy vs JSON.parse(JSON.stringify()) vs structuredClone AP_Object.assign(origArr) (version: 0)

FIguring out the performance differences between using the operations in the name on copying an array of objects considering the fact that other methods of copying (slice, concat, etc.) are shallow copies and end up being by reference instead of by value.

Comparing performance of: angular.copy() vs JSON.parse(JSON.stringify()) vs structuredClone(origArr) vs Object.assign(origArr)

Autogenerated LLM Summary (model llama3.2:3b, generated one year ago):

LLMs can make mistakes. Check important info.

It seems like you're providing information for benchmarking different methods of cloning or copying JavaScript objects, specifically:

* `angular.copy()`
* `JSON.parse(JSON.stringify())`
* `structuredClone()`
* `Object.assign()` (specifically with `origArr` as the input)

You've also provided some raw data that appears to be a JSON object and some HTML code.

Here are my answers based on the information you've provided:

### Input Data

```json
var origArr = [
  {
    categoryType: 'Patient Event',
    timeSlotId: 42,
    location: {
      locationName: 'GVH-EastWing 1A',
      locationGuid: 76600610,
    },
    resources: [
      {
        resourceId: 1,
        resourceName: 'Ongmore, John',
        resourceType: 'P',
        isAnchorResource: false,
      },
      {
        resourceId: 55,
        resourceName: 'Patel, Arpan',
        resourceType: 'P',
        isAnchorResource: true,
      },
    ],
    patient: null,
    additionalInformation: '',
    resourceId: 55,

    endTime: '2023-11-03T22:40:00',
    duration: 300,
    sourceType: 'ReserveTime',
    category: {
      type: 'ReserveTime',
      value: 'Patient Event',
    },
  },
  {
    start: '2023-11-03T21:40:00.000Z',
    end: '2023-11-04T02:40:00.000Z',
    resourceId: 55,
    slotIndex: 340,
  },
];

var newArr = [];
```

### Individual Test Cases

Here are the individual test cases with their corresponding benchmark definitions:

#### Angular Copy

{
  "Benchmark Definition": "newArr = angular.copy(origArr);",
  "Test Name": "angular.copy()"
}
```
#### JSON.parse(JSON.stringify())
```javascript
{
  "Benchmark Definition": "newArr = JSON.parse(JSON.stringify(origArr));",
  "Test Name": "JSON.parse(JSON.stringify())"
}
```
#### structuredClone()
```javascript
{
  "Benchmark Definition": "newArr = structuredClone(origArr);",
  "Test Name": "structuredClone(origArr)"
}
```
#### Object.assign()
```javascript
{
  "Benchmark Definition": "newArr = Object.assign(origArr);",
  "Test Name": "Object.assign(origArr)"
}
```
