react if else ternary code example
Example 1: if else render react
render() {
const isLoggedIn = this.state.isLoggedIn;
return (
<div>
{isLoggedIn ? (
<LogoutButton onClick={this.handleLogoutClick} />
) : (
<LoginButton onClick={this.handleLoginClick} />
)}
</div>
);
}
Example 2: 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.
