angular.copy vs JSON.parse(JSON.stringify()) vs structuredClone AP (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.

LLMs can make mistakes. Check important info.

It appears you're providing a detailed benchmarking report, which includes:

1. The original data (in JSON format) for an AngularJS array (`origArr`) and its HTML template code.
2. Individual test cases with their corresponding Benchmark Definitions and Test Names.
3. The latest benchmark result with the execution speed for each test case.

To provide a helpful response, I'll need to make some assumptions:

* You want me to analyze the data and determine which method (angular.copy(), JSON.parse(JSON.stringify()), or structuredClone()) is the fastest in terms of execution speed.
* You'd like me to recommend the best approach based on the benchmark results.

Here's my analysis:

**angular.copy()**: The first test case shows an execution speed of 19225.724609375 executions per second, which is the highest among all three methods. This suggests that `angular.copy()` is the fastest way to create a shallow copy of the original array.

**JSON.parse(JSON.stringify())**: The second test case has an execution speed of 6919.5322265625 executions per second, which is slower than `angular.copy()`. However, this method can be useful when dealing with nested objects and arrays, as it serializes the data to a string and then parses it back into an object.

**structuredClone()**: The third test case has an execution speed of 4852.3916015625 executions per second, which is slower than `angular.copy()` but faster than `JSON.parse(JSON.stringify())`. This method is a relatively new addition to the Web APIs and can be useful in certain scenarios where `JSON.parse(JSON.stringify())` is not sufficient.

Based on the benchmark results, I would recommend using **angular.copy()** for creating shallow copies of AngularJS arrays. However, if you need to work with nested objects or arrays, `structuredClone()` might be a better option due to its performance advantage over `JSON.parse(JSON.stringify())`.

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.
