Script Preparation code:

var itemsArray = [];

for (let i = 0; i < 100000; i++) {
	itemsArray.push({
    	used: i,
      	free: i,
      	total: i + i,
    })
}

Tests:

lodash sum
const data = { a: _.sumBy(itemsArray, item => item.used), b: _.sumBy(itemsArray, item => item.free), c: _.sumBy(itemsArray, item => item.total), } console.log(data)
native sum
let a = 0; let b = 0; let c = 0; itemsArray.forEach((item) => { a += item.used; b += item.free; c += item.total; }) console.log({a, b, c})
lodash for each
let a = 0; let b = 0; let c = 0; _.forEach(itemsArray, (item) => { a += item.used; b += item.free; c += item.total; }) console.log({a, b, c})
