const div = document.querySelector('div');	// select the parent
const p = document.createElement('p');	// create or select the child
p.textContent = 'Some Text!';	// add some juicy text to it
div.prepend(p);	// prepend the child at the top of the parent

// Basically what that means is:
parent.prepend(child)
