Benchmark: _pickBy vs native Object.entries + filter

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var obj = Array(1000)
  .fill()
  .reduce((acc, curr, i) => {
    acc[i] = i;
    return acc;
  }, {});
var predicate = v => v % 2 === 0;

Tests:

_.pickBy
_.pickBy(obj, predicate);
filter
Object.entries(obj).filter(([_, v]) => predicate(v));
reduce
Object.entries(obj).reduce((acc, [k, v]) => { if (predicate(v)) acc[k] = v; return acc; }, {});
