Benchmark: Perfomance: Switch (with functions) vs Polymorphism (with methods)

Script Preparation code:

var class1 = {
    GetImportantValue: () => 1
};
var class2 = {
    GetImportantValue: () => 2
};
var class3 = {
    GetImportantValue: () => 3
};
var class4 = {
    GetImportantValue: () => 4
};
var class5 = {
    GetImportantValue: () => 5
};

function GetImportantValue1() {
    return 1;
}

function GetImportantValue2() {
    return 2;
}

function GetImportantValue3() {
    return 3;
}

function GetImportantValue4() {
    return 4;
}

function GetImportantValue5() {
    return 5;
}

getImportantValueSwitch = (myClassEnum) => {
    switch (myClassEnum.type) {
        case 'MyClass1':
            return GetImportantValue1();
        case 'MyClass2':
            return GetImportantValue2();
        case 'MyClass3':
            return GetImportantValue3();
        case 'MyClass4':
            return GetImportantValue4();
        case 'MyClass5':
            return GetImportantValue5();
    }
}

getImportantValuePolymorphism = (myClass) => myClass.GetImportantValue();

Tests:

Polymorphism
getImportantValuePolymorphism(class1); getImportantValuePolymorphism(class2); getImportantValuePolymorphism(class3); getImportantValuePolymorphism(class4); getImportantValuePolymorphism(class5);
Switch
getImportantValueSwitch({type: 'MyClass1'}); getImportantValueSwitch({type: 'MyClass2'}); getImportantValueSwitch({type: 'MyClass3'}); getImportantValueSwitch({type: 'MyClass4'}); getImportantValueSwitch({type: 'MyClass5'});
