- Use Array.prototype.slice() to get an array containing the nth element at the first place.
- If the index is out of bounds, return undefined.
- Omit the second argument, n, to get the first element of the array.
//#Source https://bit.ly/2neWfJ2 const nthElement = (arr, n = 0) => (n > 0 ? arr.slice(n, n + 1) : arr.slice(n)); console.log(nthElement(['a', 'b', 'c'], 1)); console.log(nthElement(['a', 'b', 'b'], -3));
