Benchmark: larger map vs if vs switch

Script Preparation code:

var map = new Map([
    [0, 1],
    [1, 0],
    [2, 0],
    [3, 1],
    [4, 1],
    [5, 0],
    [6, 1],
    [7, 0],
    [8, 0],
    [9, 1],
    [10, 1],
    [11, 0]
]);

function switchCase(value) {
    switch (value) {
        case 0:
            return 1;
        case 1:
            return 0;
        case 2:
            return 0;
        case 3:
            return 1;
        case 4:
            return 1;
        case 5:
            return 0;
        case 6:
            return 1;
        case 7:
            return 0;
        case 8:
            return 0;
        case 9:
            return 1;
        case 10:
            return 1;
        default:
            return 0
    }
}

function ifElse(value) {
    if (value === 0 || value === 3 || value === 4 || value === 6 || value === 9 || value === 10) {
        return "Initializing";
    }

    return "Running"
}

Tests:

map lookup
let value = map.get(0); value = map.get(32); value = map.get(1);
switch case
let value = switchCase(0); value = switchCase(32); value = switchCase(1);
if/else
let value = ifElse(0); value = ifElse(32); value = ifElse(1);
