When a DOM element is used as a placeholder, Vomit will simply append this child element into the DOM element returned.
var span = document.createElement('span')
span.innerHTML = 'Hello world!'
vomit`<button>${span}</button>`
// or even better
var span = vomit`<span>Hello world!</span>`
vomit`<button>${span}</button>`result:
<button><span>Hello world!</span></button>Vomit interfaces organically with all native APIs when some other libraries force you to use closed abstraction that do not play well with others. Element placeholders and functions are the perfect cocktail to create complex applications.
