Concatenate unicode and variable

Question

I'm newbie in React and I have some issue to display dynamic unicode value ?

{'\u{1F680}'} become {'\u{MyVar}'}

Answer 1

String.fromCodePoint will get you the character from its numeric code point, and parseInt will get you the number from a hex string.

Your conversion will look like the following : String.fromCodePoint(parseInt(MyVariable, 16))

Working example :

const App = ({ unicode }) => <p> 3, 2, 1, GO ! {String.fromCodePoint(parseInt(unicode, 16))}</p>

ReactDOM.render(<App unicode='1F680'/>, document.getElementById('root'))
