Standard DOM API

const div = document.createElement('div');
div.className = 'card';
div.textContent = 'Hello World';
div.setAttribute('id', 'intro');
div.onclick = () => console.log('Hi');

JJ (Just JavaScript)

JJHE.create('div')
    .addClass('card')
    .setText('Hello World')
    .setAttr('id', 'intro')
    .on('click', () => console.log('Hi'))
