Script Preparation code:

var types = {
    array: [1, 2, 3],
    number: 123,
    string: '123',
    map: new Map([
        [1, 1],
        [2, 2],
        [3, 3]
    ]),
    set: new Set([1, 2, 3]),
    buffer: new ArrayBuffer([1, 2, 3]),
    boolean: true,
    arrow: () => {},
    function: function() {},
    object: {}
}

var values = Object.values(types)

Tests:

typeof -> object
values.map(value => typeof value === "object" && !Array.isArray(value) && value !== null)
Object.prototype.toString.call -> object
values.map(value => Object.prototype.toString.call(value) === '[object Object]')
