Use const to create a variable named song and assign it result of the find() method call on the userData?.songs array. Use song as the parameter of the find() callback and check if song.id is strictly equal to id.

This will iterate through the userData?.songs array, searching for a song that corresponds to the id passed into the playSong function.

Hi @email2shaheer

Use the example from the instructions to structure your code:

const foundNumber = numbers.find((number) => number > 25);

For next time, describe the issue in your own words. Learning to communicate problems is a part of becoming a web developer.

Happy coding

it worked however in ur given example it would be
const number = user?.numbers.find((number) => number.id ===id);

the basic structure is valid but the concoctations are different
