Benchmark Explanation

The provided benchmark measures the performance difference between two approaches to achieve object destruction in JavaScript: native object destruction and using the Lodash library's omit function.

Native Object Destruction

In this approach, an object is created with three properties (a, b, and c) and then destructured using a syntax similar to ES6 destructuring. The resulting object without the unwanted properties (result2) is returned from the function. This approach relies on JavaScript's native syntax for object destruction.

Pros of Native Object Destruction

1. Efficient: Native object destruction is typically faster since it doesn't involve any additional library calls or overhead.
2. Low Overhead: The code required to implement this approach is minimal, with only a few lines needed to create the object and destructure it.

Cons of Native Object Destruction

1. Limited Browser Support: Older browsers may not support ES6 features like destructuring, which could result in slower performance or errors.
2. Less Intuitive for Non-Experienced Developers: While familiar to those with experience in JavaScript, this approach might seem less intuitive for developers without prior knowledge of object destruction.

Lodash Omit

In contrast, the Lodash library's omit function is used to achieve object destruction. This approach involves calling a separate library function and passing an array of keys to exclude from the original object.

Pros of Lodash Omit

1. Wide Browser Support: As a widely used library, Lodash is supported by most modern browsers.
2. Easy to Use: For developers familiar with the Lodash library, using omit can be straightforward and efficient.

Cons of Lodash Omit

1. Additional Library Overhead: Calling an external function introduces additional overhead compared to native object destruction.
2. Less Efficient: Since it involves a separate library call, this approach might be slower than native object destruction.

Library Description - Lodash

Lodash is a popular JavaScript utility library that provides various functions for tasks such as array manipulation, object modification, and more. The omit function specifically returns a new object with the specified keys removed from the original object.

Other Considerations

1. ES6 Features: This benchmark assumes familiarity with ES6 syntax like destructuring. If you're using older JavaScript versions or a different programming paradigm, this approach might not be feasible.
2. Performance Variance Across Browsers: As seen in the benchmark results, performance can vary significantly across browsers and devices.

Alternatives to Native Object Destruction

If native object destruction is not an option, other approaches could include:

1. Using Object.assign() with a new object that excludes unwanted properties.
2. Implementing a custom delete function for objects.
3. Utilizing libraries like Lodash or a similar utility library to perform object manipulation.

Keep in mind that these alternatives may have their own trade-offs in terms of efficiency, browser support, and overall performance.
