section: what is react
- the
<div />
syntax is transformed at build time toReact.createElement('div')
.
for example
class ShoppingList extends React.Component {
render() {
return (
<div className="shopping-list">
<h1>Shopping List for {this.props.name}</h1>
<ul>
<li>Instagram</li>
<li>WhatsApp</li>
<li>Oculus</li>
</ul>
</div>
);
}
}
it's equivalent to
return React.createElement('div', {className: 'shopping-list'},
React.createElement('h1', /* ... h1 children ... */),
React.createElement('ul', /* ... ul children ... */)
);
- the
render()
element should havereturn
