Let's break down the benchmark and its options.

Benchmark Purpose: The benchmark compares the performance of two approaches to check for equality between two arrays of strings:

1. _.isEqual from Lodash library
2. Using JSON.stringify() with shallow equality comparison (===)

Lodash _.isEqual:

• The _._isEqual function is a utility function that checks if two values are equal.
• It recursively traverses the objects and compares their properties, taking into account various data types like numbers, strings, booleans, and arrays.

Pros:

• Handles complex data structures, including nested arrays and objects.
• Optimized for performance.

Cons:

• Requires Lodash library to be included in the script, which may add extra overhead.
• May not perform well with very large datasets due to its recursive nature.

JSON.stringify() with shallow equality comparison:

• This approach uses JSON.stringify() to convert both arrays into a string representation and then compares these strings using the === operator.
• Since JSON.stringify() only considers primitive values, it will not recursively traverse objects or arrays.

Pros:

• Fast and efficient for simple array comparisons.
• Does not require an additional library.

Cons:

• May not handle complex data structures accurately, as it relies on shallow equality comparison.
• Performance may degrade with large datasets due to the string conversion step.

Other considerations:

• The benchmark uses a shallow array of strings (['cat', 'dog', 'bird']) for both arrays. This is a simple and common use case, but it might not be representative of more complex scenarios.
• Lodash's _._isEqual function has a built-in tolerance mechanism to account for minor differences in values due to floating-point arithmetic or string formatting issues.

Browser-specific details:

In this benchmark, the _.isEqual test uses Chrome 83 on Windows, which might have some optimizations or bugs that affect performance. The JSON.stringify test also runs on the same browser and device platform, but without any additional library or configuration.

Alternatives and further options:

• Instead of using Lodash's _._isEqual, you could use built-in JavaScript functions like === (shallow equality) or more advanced checks like Object.is() or Array.prototype.every().
• For the JSON.stringify approach, you might consider using more advanced string comparison methods, such as string comparison techniques or even regular expressions to handle edge cases.
• To improve the benchmark's accuracy and relevance, it could include additional test cases with different data structures (e.g., objects, dates, numbers, etc.) or more complex scenarios (e.g., nested arrays, objects with properties).
