Benchmark: Compare the new ES6 spread operator with Ramda assoc using reduce

HTML Preparation code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.25.0/ramda.js"></script>

Script Preparation code:

var translations = [...Array(500).keys()].map((key) => ({term: ''+Math.random(), translation: '' + Math.random()}));
var data = {iso: 'foof', translations};

Tests:

reduce + spread operator
JSON.stringify( data.translations.reduce((acc, x) => ({ ...acc, [x.term]: x.translation }), {}), null, 4, )
for
var trans = {}; for (const x of data.translations) { trans[x.term] = x.translation; } JSON.stringify(translations, null, 4)
assoc + reduce
JSON.stringify( data.translations.reduce((acc, x) => R.assoc(x.term, x.translation, acc), {}), null, 4, )
