Welcome to the community @achintyazen !

Good attempt!

If you use this example, from the step, as guidance (replacing what is necessary with the information provided in the instructions, your code should pass.

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

song should replace foundNumber for starters.

I hope this helps you.

To assign the result of the find method to a variable, you can simply do it like this:

const playSong = (id) => {
  const song = array.find(item => item.id === id);
  // Use the 'song' variable here
};

In the above code:

  • array is the array you want to search in.
  • find is a method that takes a callback function. This function is applied to each element in the array until one is found where the callback returns true. It returns the first matching element, or undefined if no match is found.
  • Inside the callback function, item represents each element of the array as the find method iterates over it.
  • item.id === id is the condition we’re checking. It compares the id property of each element with the id passed to the playSong function.

i hope it will be helpfull for you
