Array.prototype.find()

The find method returns the first element that satisfies the condition that is checked by the callback function.

The callback function is called with three parameters. The first parameter is the current element, the second parameter is the current index and the last parameter is the array itself it is called with.

Example:

function findNegativeNumber(currentElement) {
  return currentElement < 0 // The first element to satisfies this condition will be returned by the find method.
}

const numbers = [40, 30, -19, 10, -2, 9]

const firstNegativeNumber = numbers.find(findNegativeNumber)

console.log(firstNegativeNumber) // -19
