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

Ramda vs. Lodash (Fixed & IIFE updated zero) (version: 0)

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 = Array(10000).fill(0).map(function(x, 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
const result = []; for (const { counter } of data) { if (isOdd(counter)) { const s = square(counter); if (lessThanThreeDigits(s)) { result.push(s); } } }
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))));
Native pipe
const result = data.map(({counter}) => counter).filter(isOdd).map(square).filter(lessThanThreeDigits);
