Benchmark Explanation

The provided JSON represents a benchmark test on MeasurThat.net, comparing the performance of two approaches to determine if a string matches a specific sorting order.

Approaches Compared

There are two approaches being compared:

1. String-to-Value: This approach checks if the sortTypeSelected variable is equal to one of the values in the SortTypes object.
2. ValueArray-to-String: This approach checks if the sortTypeSelected variable is included in an array of values from the SortTypes object.

Options Compared

The two approaches are compared by executing the corresponding JavaScript code. The benchmark results show that the "Compare string-to-value" test has a higher number of executions per second than the "Compare valueArray-to-string" test.

Pros and Cons

• String-to-Value Approach: Pros:
  • Simple to implement
  • Fast execution (higher executions per second) Cons:
  • May be slower for large datasets or complex sorting orders
• ValueArray-to-String Approach: Pros:
  • More robust for handling multiple values in the sorting order
  • May be faster for larger datasets or more complex sorting orders Cons:
  • Slower execution (lower executions per second)

Library and Purpose

There is no explicit library mentioned in the provided JSON. However, it's likely that the SortTypes object is a custom object created by the benchmark author.

Special JS Features/Syntax

The benchmark uses JavaScript variables (var, sortTypeSelected) and array notation ([SortTypes.Created, SortTypes.Updated].includes( sortTypeSelected )). These are standard features of modern JavaScript, but not explicitly mentioned in the explanation for wider audiences.

Other Alternatives

If the "Compare string-to-value" or "Compare valueArray-to-string" approaches were not used, alternative methods could include:

• Using regular expressions to match strings against patterns
• Utilizing a more efficient data structure, such as a Trie, for matching values
• Employing a different sorting algorithm (e.g., merge sort, quick sort) for comparison

However, these alternatives are not explicitly mentioned in the provided JSON or benchmark results.
