To create the checkbox dynamically using JavaScript, we use the createElement method.
For instance, we write
const checkbox = document.createElement("input");
checkbox.type = "checkbox";
checkbox.name = "name";
checkbox.value = "value";
checkbox.id = "id";
to create an input element with createElement.
We set its type attribute to 'checkbox' to make it a checkbox by setting the type property.
Then we set its name, value and id attributes by setting the properties with the same name.
