Benchmark created on

Setup

let map = new Map();
let obj = {};
let size = 5e6;

const benchMarkMapSet = size => {
for (let i = 0; i < size; i++) {
    map.set(i, i);
}
};

const benchMarkObjSet = size => {
for (let i = 0; i < size; i++) {
    obj[i] = i;
}
};

const benchMarkMapGet = size => {
for (let i = 0; i < size; i++) {
    let x = map.get(i);
}
};

const benchMarkObjGet = size => {
for (let i = 0; i < size; i++) {
    let x = obj[i];
}
};

Teardown

map = new Map();
obj = {};
