Benchmark Overview

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks, comparing the performance of different approaches to solve specific problems. The provided benchmark definition json measures the speed of Ramda's map function versus the native map function in JavaScript arrays.

Options Compared

The benchmark compares two options:

1. Ramda's map function: A functional programming library that provides a more expressive and concise way to perform operations on arrays.
2. Array's native map function: The built-in array method for applying a transformation function to each element of an array.

Pros and Cons

• Ramda's map function:
  • Pros: More expressive and concise syntax, easier to read and write code, provides additional features like curry and memoize.
  • Cons: Additional overhead due to the functional programming library, might be slower than native array methods.
• Array's native map function:
  • Pros: Built-in performance, no additional overhead, simple and straightforward syntax.
  • Cons: More verbose syntax compared to Ramda's map, less expressive.

Library Used

In this benchmark, the library used is Ramda, a functional programming library for JavaScript. Ramda provides a set of higher-order functions that can be composed together to solve problems in a more declarative and concise way.

Special JS Feature or Syntax

There are no special JavaScript features or syntax mentioned in this benchmark definition. Both options, Ramda's map function and Array's native map, use standard JavaScript syntax.

Other Alternatives

If you prefer not to use Ramda, there are other functional programming libraries for JavaScript that provide similar functionality, such as:

• Lodash
• Underscore.js

Alternatively, you can also use ES6-style array methods, which provide a more concise and expressive way to perform operations on arrays, such as map, filter, and reduce.
