Run results for: Ramda vs. Lodash vs vanilla js

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.

function isOdd(num) {
  return num % 2 === 1;
}

function square(num) {
  return num * num;
}

function lessThanThreeDigits(num) {
  return num.toString().length < 3;
}

Tests:

Vanilla Js
var result = data.map(square)
Ramda without relying on currying or composition
var result = R.map(square)(data)
Ramda with currying and composition
var result = R.pipe( R.map(square) )(data);
Lodash
var result = _.chain(data) .map(square)
