Benchmark: Ramda vs. Lodash (Fixed & IIFE updated asc)

Ramda vs. Lodash (Fixed & IIFE updated asc) (version: 3)

Compares performance on the same task using Lodash vs two styles of Ramda vs two styles of "native" Javascript. In all cases the task is pulling "counter" property from each item in an array, filtering out odd items, squaring them, then returning those squared values that have less than two digits.

Script Preparation code:

var data = _.range(10000).map(function(i) {
  return {
    counter: i
  }
});

function isOdd(num) {
  return num % 2 === 1;
}

function square(num) {
  return num * num;
}

function lessThanThreeDigits(num) {
  return num.toString().length < 3;
}

Tests:

Native
var result = (() => { var result = []; var { length } = data; for (var i = 0; i < length; i++) { var { counter } = data[i]; if (!isOdd(counter)) { continue; } var s = square(counter); if (!lessThanThreeDigits(s)) { continue; } result.push(s); } return result; })()
Lodash
var result = _.chain(data) .map('counter') .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .value();
Ramda with currying and composition
var result = R.pipe( R.pluck('counter'), R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits) )(data);
Ramda
var result = R.filter(lessThanThreeDigits, R.map(square, R.filter(isOdd, R.pluck('counter', data))));
