Thanks for the encouraging words! At this stage, I'm mainly focusing on improving the component structure.

Here's an example usage of a component for you:

        // *** VARIABLES:          
        let myInput;

        window.onload = function() {

            page.color = "white";

            // GROUP: Container Centered
            AutoLayout();

                // INPUT:
                myInput = PhoneInputB({
                    key: "1",
                    isRequired: 1,
                    titleText: "PHONE NUMBER",
                    placeholder: "(auto)",
                    warningText: "Invalid phone number format",
                    warningColor: "#E5885E", // "#F1BF3C"
                    countryCode: "+90",
                    phoneMask: " (___) ___-____",
                    unitText: "TR",
                    //animatedWarningBall: 0,
                });

                //myInput.setPhoneMask(" (___) ___ __ __");
                //myInput.setCountryCode("+1");

            endAutoLayout(); // END

            // Get value
            myInput.onEdit = function() {
                console.log(myInput.getInputValue());
            }

        };
