Benchmark: ES6 equivalent to lodash _.mapValues

HTML Preparation code:

<script src="https://raw.githubusercontent.com/lodash/lodash/4.17.15-npm/core.js"></script>

Tests:

native approach with reduce
var fruits= { 'apple': { 'name': 'apple', 'number': 5}, 'orange': { 'name': 'orange', 'number': 10 } }; console.log(Object.entries(fruits) .reduce((a, [key, { number }]) => { a[key] = number; return a; }, {} ));
native approach fromEntries
var fruits= { 'apple': { 'name': 'apple', 'number': 5}, 'orange': { 'name': 'orange', 'number': 10 } }; console.log(Object.fromEntries( Object.entries(fruits).map(([key, { number }]) => [key, number]) ));
lodash mapValues
var fruits= { 'apple': { 'name': 'apple', 'number': 5}, 'orange': { 'name': 'orange', 'number': 10 } }; _.mapValues(fruits, 'number');
