Benchmark: array find vs lodash find vs object lookup vs object.sub_property lookup

HTML Preparation code:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.core.js"></script>

Script Preparation code:

var size = 1000;
var searchForID = 'id500';
var searchFor = {
    id: searchForID
};

var arr = [size];
var obj = {};
var objTree = {
    sub: {}
};

for (var i = 0; i < size; i++) {
    let entry = {
        id: 'id' + i,
        value: 'value' + i
    };
    arr.push(entry);
    obj['id' + i] = entry;
    objTree.sub['id' + i] = entry;
}

Tests:

array find by value
arr.find(item => item.id === 'id500');
array find by var
arr.find(item => item.id === searchFor.id);
lodash _.find by value
_.find(arr, {id: 'id500'});
lodash _.find by var
_.find(arr, {id: searchFor.id});
object lookup by value
obj['id500'];
object lookup by var
obj[searchFor.id];
object.sub lookup by value
objTree.sub['id500'];
object.sub lookup by var
objTree.sub[searchFor.id];
