Introducing template-driven forms

Angular provides you with two different ways to add forms to an application. A very easy way of creating forms is to use templates, which Angular calls template-driven forms. By using these templates, we can add some directives to form elements as well as functionality such as value accessing and validations. In this section, we will be creating one of these forms.

<form>
    <h1 class="is-size-3">Add New Flash Card</h1>
    <div class="field">
        <label class="label" for="">Question</label>
        <div class="control">
            <input required class="input" type="text" 
          ...
