Call your functions using instanceof operator (drunk programming only)

// Drunk programming only
class DrunkInstanceof {
    constructor(customFunction) {
        this.customFunction = customFunction;
    }

    [Symbol.hasInstance](arg) {
        return this.customFunction(arg);
    }

    get [Symbol.toStringTag]() {
        return `DrunkInstanceof`;
    }

    toString() {
        return `[Object DrunkInstanceof]`;
    }
}

module.exports = customFunction => {
    return new DrunkInstanceof(customFunction);
}
