Benchmark: find vs dict vs arr

Script Preparation code:

var arr = [];
var dict = {};

for (let i = 0; i < 100; i++) {
    arr.push({ id: i, char: 'foo' + i });
    dict[i] = { id: i, char: 'foo' + i };
}

Tests:

Find
var v1 = arr.find(x => x.id === 5); var v2 = arr.find(x => x.id === 54); var v3 = arr.find(x => x.id === 89);
Array
var v1 = arr[5]; var v2 = arr[54]; var v3 = arr[89];
Dictionary
var v1 = dict[5]; var v2 = dict[54]; var v3 = dict[89];
