Filter Elements from Array in Javascript - 30-Day Leetcode Challenge #6
Given an integer array arr and a filtering function fn, return a filtered array filteredArr.
The fn function takes one or two arguments:
arr[i] - number from the arr
i - index of arr[i]
filteredArr should only contain the elements from the arr for which the expression fn(arr[i], i) evaluates to a truthy value. A truthy value is a value where Boolean(value) returns true.
Please solve it without the built-in Array.filter method.
