Benchmark Overview
The provided JSON represents a JavaScript microbenchmarking test case on the MeasureThat.net website. The benchmark compares the performance of two approaches: Array.prototype.map
and Lodash.map
. The purpose of this benchmark is to measure which approach is more efficient in terms of execution time.
Options Compared
The two options being compared are:
Array.prototype.map
: This method is a built-in method of the Array prototype in JavaScript, used to create a new array with the results of applying a provided function on every element in this array.Lodash.map
: This is a utility function from the Lodash library, also used to transform an array by applying a provided function.Pros and Cons
map
method on arrays.Library Usage
In this benchmark, the lodash.js
library is used to provide the _.map()
function. Lodash is a popular utility library for JavaScript that provides a wide range of functions for tasks like array manipulation, string manipulation, and more.
Special JS Features/Syntax
This benchmark does not use any special JavaScript features or syntax beyond what is commonly available in modern browsers.
Other Alternatives
If you wanted to create an alternative benchmark to compare the performance of Array.prototype.map
and Lodash.map
, you might consider:
map()
that takes advantage of native WebAssembly support.Array.prototype.forEach()
or Set
.Ramda
instead of Lodash.Keep in mind that each alternative would require significant changes to the benchmark and potentially affect its accuracy or relevance.
