Django Rendering Forms Manually and using csfr token

<form action="{% url "submit-form-url-name" %}" method="post" accept-charset="utf-8">
    {% csrf_token %}
    {{ form.field1 }}
    {{ form.field2 }}
    ...
</form>

function getCookie(name) {
    let cookieValue = null;
    if (document.cookie && document.cookie !== '') {
        const cookies = document.cookie.split(';');
        for (let i = 0; i < cookies.length; i++) {
            const cookie = cookies[i].trim();
            // Does this cookie string begin with the name we want?
            if (cookie.substring(0, name.length + 1) === (name + '=')) {
                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                break;
            }
        }
    }
    return cookieValue;
}
const csrftoken = getCookie('csrftoken');
