.find()

The .find() method returns the first element in the array that satisfies the given function.

array.find(function);

The function is a callback that is applied to each element as the array is traversed. If no valid element is found, undefined is returned.

const temperature = [72, 87, 92, 90, 85, 88, 81];

const hot = temperature.find((element) => element >= 90);

console.log(hot);
// Output: 92
