conditional statement react native code example
Example 1: react native conditional rendering
class Component extends React.Component {
const a = true
render() {
return (
<Container>
{a == true
? (<Button/>)
: null
}
</Container>
)
}
}
This is staying: if a == true, render a button component.
Otherwise render null, in other words nothing.
Example 2: react native conditional rendering
function Mailbox(props) {
const unreadMessages = props.unreadMessages;
return (
<div>
<h1>Hello!</h1>
{unreadMessages.length > 0 &&
<h2>
You have {unreadMessages.length} unread messages.
</h2>
}
</div>
);
}
