Let's break down what's being tested in the MeasureThat.net benchmark.

The benchmark compares two approaches to accessing nested properties in JavaScript:

1. Lodash.get: This is a utility function from the Lodash library, which helps with chaining method calls on objects. The get function takes an object and a path as arguments and returns the value at that path.
2. Native Property Access: This approach uses dot notation to access nested properties directly on the person object.

What's being tested:

The benchmark is testing which approach (Lodash.get or Native Property Access) performs better in terms of speed, specifically with longer paths (e.g., "name.something.else").

Pros and Cons:

• Lodash.get: Pros:
  • Provides a concise and readable way to access nested properties.
  • Can be useful when working with complex object structures.
• Cons:
  • Requires including the Lodash library, which may add overhead.
  • May not perform as well for very deep or large objects due to function call overhead.
• Native Property Access: Pros:
  • No additional library required.
  • Typically faster than using a library like Lodash for simple property access scenarios.
• Cons:
  • Requires chaining multiple dot notation calls, which can make the code harder to read.

Library Considerations:

Lodash is a popular utility library that provides various functions for working with JavaScript objects. The get function is particularly useful when you need to dynamically access nested properties on an object.

Special JS Feature/ Syntax:

This benchmark does not use any special JavaScript features or syntax, such as async/await, generators, or ES6+ classes.

Other Alternatives:

If you don't want to use Lodash, you can also consider other alternatives for accessing nested properties in JavaScript, such as:

• Using a custom function with a loop to iterate through the object's property chain.
• Employing a recursive function to access deeply nested properties.
• Leveraging modern JavaScript features like Object.prototype.hasOwnProperty.call or in operator.

Keep in mind that these alternatives may have different performance characteristics compared to using Lodash or native property access.
