I'm a beginner so I apologize for the "easy" question. Thank you.

```js
let majority = (arr, call) => {

  let reducedArr = arr.reduce(function(accu, item, index) {
    if (call(item) >= index) {
      return true
    } else {
      return false
    }
  })
}

const isOdd = function(num) {
  return num % 2 === 1;
};

console.log(majority([1, 2, 3, 4, 5], isOdd)); // should log: true
console.log(majority([2, 3, 4, 5], isOdd)); // should log: false
```
