conditionals in react js value code example
Example 1: how to use if else inside jsx in react
renderElement(){
if(this.state.value == 'news')
return <Text>data</Text>;
return null;
}
render() {
return (
<View style={styles.container}>
{ this.renderElement() }
</View>
)
}
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.
