How do I make text bold, italic, or underline in React Native?

Question

Surprisingly there isn't one question that groups these all together yet on Stack Overflow; there hasn't been an answer on SO for italics or underline, in fact, only this question for bold. I self-answered this quesiton below.

Answer 1

<Text style={styles.bold}>I'm bold!</Text>
<Text style={styles.italic}>I'm italic!</Text>
<Text style={styles.underline}>I'm underlined!</Text>

const styles = StyleSheet.create({
    bold: {fontWeight: 'bold'},
    italic: {fontStyle: 'italic'},
    underline: {textDecorationLine: 'underline'}
})
