    name: 'input',
    class: ['input', 'input-form'],
    attr: {
        id: 'email',
        type: 'email',
        name: 'email',
        required: true,
        placeholder: 'Email',
    },
    style: "color: blue", // inline css
    draggable: true,
    trackMutation: true // See for any changes on the element
}, e => {
    e.addEventListener('change', () => {
        if (Validate.validateEmailAddress(e.value)) {
            console.log("Email: pass!");
        } else {
            console.log("Enter correct email pls!");
        } // Using form Validate method
    });
});

document.body.appendElement(emailInput);

and in html:

<script src="./butility.js" type="module"></script>
<script>
    import { Utility, DeviceAPIs } from "./butility.js"
    const button = document.querySelector('button');
    const input = document.querySelector('input');
    Utility.toggleClassOnGeolocationChange(button, "changed-location", {
        // Optional
        enableThrottling: true,
        throttleInterval: 6000,
        onClassToggle: function() {
            // Change UI
            console.log("changing UI")
        },
        onError: function() {
            // Do something
        }
    });

    // Device APIs
    DeviceAPIs.writeToClipboard(input.value)
    DeviceAPIs.readFromClipboard().then(res => console.log(res)); // Read data from the clipboard
</script>

Each module is packed with helpful methods that make your web development life easier.
