Run results for: JS native vs js native loop vs Ramda vs. Lodash 4

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.

Tests:

JS native
var result = data .map(({counter}) => counter) .filter(isOdd) .map(square) .filter(lessThanThreeDigits)
Ramda with transducer
var transducer = R.compose ( R.map(R.prop('counter')), R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits), ); var result = R.transduce ( transducer, (acc, val) => { acc.push(val); return acc; }, [], data, );
Ramda with transducer (no prop)
var transducer = R.compose ( R.map(({counter}) => counter), R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits), ); var result = R.transduce ( transducer, (acc, val) => { acc.push(val); return acc; }, [], data, );
Ramda with currying and composition
var result = R.pipe( R.pluck('counter'), R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits) )(data);
Ramda without relying on currying or composition
var result = R.filter(lessThanThreeDigits, R.map(square, R.filter(isOdd, R.pluck('counter', data))));
Ramda with currying and composition (no pluck)
var result = R.pipe( R.map (({counter}) => counter), R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits) )(data);
Lodash
var result = _.chain(data) .map('counter') .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .value();
js native loop
let result = []; for (let i=0; i<data.length; i++) { const { counter } = data[i]; if (isOdd (counter)) { let squared = square (counter); if (lessThanThreeDigits (squared)) { result.push (squared); } } }
