Call your functions using instanceof operator (drunk programming only)

// Drunk programming only
+-~function() {
    class DrunkInstanceof {
        constructor(customFunction) {
            this.customFunction = customFunction;
        }
    
        [Symbol.hasInstance](arg) {
            return this.customFunction(arg);
        }
    
        get [Symbol.toStringTag]() {
            return `DrunkInstanceof`;
        }
    
        toString() {
            return `[Object DrunkInstanceof]`;
        }
    }
    
    window.InstanceOfFunction = customFunction => {
        return new DrunkInstanceof(customFunction);
    }
}();
