    factors
    Returns the array of factors of the given num. If the second argument is set to true returns only the prime factors of num. If num is 1 or 0 returns an empty array. If num is less than 0 returns all the factors of -int together with their additive inverses.
    Use Array.from(), Array.map() and Array.filter() to find all the factors of num. If given num is negative, use Array.reduce() to add the additive inverses to the array. Return all results if primes is false, else determine and return only the prime factors using isPrime and Array.filter(). Omit the second argument, primes, to return prime and non-prime factors by default.
    Note:- Negative numbers are not considered prime.

    fibonacci
    Generates an array, containing the Fibonacci sequence, up until the nth term.
    Create an empty array of the specific length, initializing the first two values (0 and 1). Use Array.reduce() to add values into the array, using the sum of the last two values, except for the first two.

    geometricProgression
    Initializes an array containing the numbers in the specified range where start and end are inclusive and the ratio between two terms is step. Returns an error if step equals 1.

    hammingDistance
    Calculates the Hamming distance between two values.
    Use XOR operator (^) to find the bit difference between the two numbers, convert to a binary string using toString(2). Count and return the number of 1s in the string, using match(/1/g).

    howManyTimes
    Returns the number of times num can be divided by divisor (integer or fractional) without getting a fractional answer. Works for both negative and positive integers.
    If divisor is -1 or 1 return Infinity. If divisor is -0 or 0 return 0. Otherwise, keep dividing num with divisor and incrementing i, while the result is an integer. Return the number of times the loop was executed, i.

+Returns the number of times `num` can be divided by `divisor` (integer or fractional) without getting a fractional answer. 
+Works for both negative and positive integers.
+
+If `divisor` is `-1` or `1` return `Infinity`.
+If `divisor` is `-0` or `0` return `0`.
+Otherwise, keep dividing `num` with `divisor` and incrementing `i`, while the result is an integer.
+Return the number of times the loop was executed, `i`.
+
+```js
+const howManyTimes = (num, divisor) => {
+  if (divisor === 1 || divisor === -1) return Infinity;
+  if (divisor === 0) return 0;
+  let i = 0;
