someRecursive

Write a recursive function called someRecursive which accepts an array and a callback. The function returns true if a single value in the array returns true when passed to the callback. Otherwise it returns false.

Solution:​

// SAMPLE INPUT / OUTPUT
// const isOdd = val => val % 2 !== 0;

// someRecursive([1,2,3,4], isOdd) // true
// someRecursive([4,6,8,9], isOdd) // true
// someRecursive([4,6,8], isOdd) // false
// someRecursive([4,6,8], val => val > 10); // false

const isOdd = (val) => val % 2 !== 0;

function someRecursive(arr, cb) {
  // add whatever parameters you deem necessary - good luck!
  if (arr.length === 0) return false;
  if (cb(arr[0])) return true;
  return someRecursive(arr.slice(1), cb);
}
