Benchmark: ramda-transducer w/mutations v2

HTML Preparation code:

<script src="https://rawgit.com/ramda/ramda/master/dist/ramda.js"></script>

Script Preparation code:

var ids = Array.from({ length: 10000 }, (_, index) => index + 1)
var isPositive = i => i % 2 === 0

Tests:

Array(map + filter)
ids.map(R.identity).filter(isPositive).map(R.inc)
ramda(map + filter)
R.pipe( R.map(R.identity), R.filter(isPositive), R.map(R.inc) )(ids)
ramda-transducer(map + filter)
const transform = R.pipe( R.map(R.identity), R.filter(isPositive), R.map(R.inc) ) R.transduce( transform, (acc, item) => { acc.push(item); return acc; }, [], ids, );
Array(combined map reduce)
ids.reduce((acc, item) => { const identity = R.identity(item) if (!isPositive(identity)) return acc acc.push(R.inc(identity)) return acc }, [])
