Benchmark: if-else vs switch vs object

Script Preparation code:

class Host {
    A = 1;
    B = 2;
    C = 3;
}

var host = new Host();

var x = Math.floor(Math.random() * 3);

function testObject(h, p) {
    const obj = {
        [h.A]: 1,
        [h.B]: 2,
        [h.C]: 3,
    }

    return obj[p];
}


function testIfElse(h, p) {
    var v = 0;
    if (p === h.A) {
        v = 1;
    } else if (p === h.B) {
        v = 2;
    } else if (p === h.C) {
        v = 3;
    }
    return v;
}

function testSwitch(h, p) {
    let v = 0;
    switch (p) {
        case h.A:
            v = 1;
            break;
        case h.B:
            v = 2;
            break;
        case h.B:
            v = 3;
            break;
    }
    return v;
}
