The benchmark currently under discussion compares two different approaches for removing a property from a JavaScript object: using the omit function from the Lodash library versus using JavaScript's object destructuring feature. Here’s a detailed explanation of what is being tested and the implications of each method.

Options Being Compared

1. Using Lodash's omit Function

   • Test Case:

     let data = { asdasd: 'template123', someOtherField: 'value1', anotherField: 'value2' };
     data = _.omit(data, 'asdasd');
     

   • Pros:
     • Readability: The omit function is very intuitive, clearly stating the intention to remove a specific property from the object.
     • Reusability: Lodash provides a wide array of utility functions, so using omit can be beneficial when handling various operations across your codebase.
   • Cons:
     • Performance: The use of a library like Lodash may introduce overhead as it incurs additional function call overhead and may not be as performant as native operations, especially for simple tasks.
     • Dependency: This approach requires including Lodash, which may not be desirable in all projects, particularly in environments where bundle size is a critical consideration.

2. Using JavaScript Object Destructuring

   • Test Case:

     let data = { asdasd: 'template123', someOtherField: 'value1', anotherField: 'value2' };
     const { asdasd: _, ...dataRest } = data;
     data = dataRest;
     

   • Pros:
     • Native: This approach uses JavaScript's built-in language features, which means no additional libraries are required.
     • Performance: Generally, destructuring can be more performant as it eliminates the overhead of calling an external function, as shown in the benchmark results.
   • Cons:
     • Complexity: For newcomers, destructuring might be less straightforward compared to the more explicit omit function, making it slightly harder to read for those not familiar with this syntax.
     • Limited Use Cases: This destructuring approach is good for certain cases but may not cover more complex use cases that the Lodash library would handle more robustly.

Benchmark Results

The benchmark results demonstrate a clear performance difference between the two approaches:

• Destructuring: 17,959,386 executions per second.
• Omit: 1,261,432 executions per second.

From the results, it's evident that the destructuring method significantly outperformed the Lodash omit function, which further reinforces the argument for using native JavaScript features when performance is a critical concern.

Conclusion

In conclusion, if you are looking to simply remove properties from objects in a performant manner and you prefer to minimize external dependencies, JavaScript's object destructuring is the clear winner in this benchmark. However, if you require greater clarity or plan to utilize multiple utilities provided by Lodash, or if you are working within a codebase that already uses it extensively, omit can still be a practical choice. Each method has its place depending on specific project needs, team familiarity with JavaScript features, and performance requirements.
