Script Preparation code:

var itemsArray = [];
var itemsObj = {};

for (let i = 0; i < 100000; i++) {
	itemsArray.push({
    	id: i,
      	author: 'Robert' + i,
    })
    itemsObj = {...itemsObj, [i]: {id: i, author: 'Robert' + i}}
}

Tests:

Get value in object by key
console.log('itemsObj ', itemsObj[59430])
Get value by filtering array
console.log(itemsArray.filter(item => item.id === 59430)[0])
Get value by mapping array
itemsArray.map(item => { if (item.id === 59430) { console.log(item) } })
Get value by forEach array
itemsArray.forEach(item => { if (item.id === 59430) { console.log(item) } })
Get value by forEach lodash array
_.forEach(itemsArray, item => { if (item.id === 59430) { console.log(item) } })
Get value by forEach object
_.forEach(itemsObj, (value ,key) => { if (key === 59430) { console.log(value) } })
Get value by forEach in value object
_.forEach(itemsObj, (value ,key) => { if (value.id === 59430) { console.log(value) } })
Get value by lodash filter in value object
console.log(_.filter(itemsObj, value => value.id > 75001))
Get value by filter in value array
console.log(itemsArray.filter(value => value.id > 75001))
Get value by lodash filter in value array
console.log(_.filter(itemsArray, value => value.id > 75001))
