What I learned

I realized you cannot use querySelectors for jQuery functionalities.

Adding a function to the input element that removes the error message immediately it detects the email was correctly formatted before submission by adding an event listener to the input. See code below:

NOTE: This function is mostly written in jQuery.

const inputValidator = () => {
    const inputValue = input.val();
    if (inputValue.match(regex)) {
        errorLabel.css("display", "none");
        errorInput.removeClass("error__input");
    }
}
input.on("input",inputValidator);

Continued development

In the coming projects, I am building more websites with better animations and focusing on learning React
