(component A is Home.jsx, component B is ChartSongs.jsx and component C is AudioPlayer.jsx)....... In component A I have an array of songs,then I passed it as props to component B
{/*The array*/}
chartData whose value was fetched from an array
{/*then i passed it as props to ChartSongs component*/}
const songTitleEl = chartData.map((data, i) =>(
<ChartSongs key={data.key} title={data.title} artiste={data.subtitle} coverarts={data.images?.coverart} index={i}/>
))
Then I shuffled the chartData array array using Fisher Yates algorithm in component C NOTE: I'm using context API to pass chartData around my components
function shuffle(arr){
for (let i = arr.length; i > 0; i--){
const j = Math.floor(Math.random() * (i + 1));
const temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
return arr;
}
Then I proceeded to updating chartData to the shuffled array with a function
function playShuffle(){
setChartData(shuffle(chartData))
}
But I got this error when playShuffle() function runs
Uncaught TypeError: Cannot read properties of undefined (reading 'title')

I'm developing a music app and i want to add a shuffle feature to my audio player. How do i resolve this?
NOTE: This is what the chartData array looks like
try it like this title={data?.title}
