Let's dive into the explanation of what's being tested in the provided JSON.
Benchmark Definition
The benchmark is designed to compare two approaches for sorting an array of strings:
sort()
method without any custom comparators or options.sort()
method with a custom comparator function that compares strings using the locale's sorting rules.Comparison
The two approaches are compared in terms of their performance, specifically the number of executions per second on a Mac OS X 10.15.7 desktop environment running Safari 15.
Options Compared
In the LocaleCompare Sort approach, an additional option is used: localeCompare()
, which allows for locale-specific sorting rules to be applied when comparing strings.
Pros and Cons
Library
In the LocaleCompare Sort approach, the String.prototype.localeCompare()
method is used. This method is part of the ECMAScript standard and provides locale-specific comparison functionality.
Special JS Feature or Syntax
There isn't any specific JavaScript feature or syntax being tested in this benchmark. The focus is on comparing two sorting approaches rather than exploring advanced features.
Other Considerations
When choosing between these approaches, consider the following:
localeCompare()
(LocaleCompare Sort).sort()
method (Simple Sort).Alternatives
If you want to explore other sorting approaches or testing scenarios, consider the following alternatives:
Array.prototype.sort()
method with a custom comparator function for more control over the sorting process.Keep in mind that MeasureThat.net is specifically designed to test JavaScript microbenchmarks, so you may want to explore other platforms for testing more general-purpose programming languages or scenarios.
