Fibonacci Number Finder algorithms, one recursive and one iterative, implemented in JavaScript
View fibonacci_number.js
// Fibonacci Number
// Objective: Find the n-Fibonacci number,
// the nth term of the Fibonacci Sequence,
// often denoted by F(n)
// For example, given the Fibonacci Sequence:
// 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377...
// F(8) = 21
// F(20) = 6765

Merge Sort implemented in JavaScript
View merge_sort.js
/* Like quick sort, merge sort also uses a divide-and-conquer,
* recursive methodology to sort an array. It takes advantage
* of the fact that it is relatively easy to merge two arrays
* in sorted order as long as each is sorted in the first place.
* 1) Recursively split the input array in half until a sub-array
* with only one element is produced.
* 2) Merge each sorted sub-array together to produce the final
* sorted array.

Quick Sort implemented in JavaScript
View quick_sort.js
/* Quick sort is an efficient, recursive divide-and-conquer
* approach to sorting an array. In this method, a pivot value
* is chosen in the original array. The array is then
* partitioned into two subarrays of values less than and
* greater than the pivot value. We then combine the result of
* recursively calling the quick sort algorithm on both
* sub-arrays. This continues until the base case of an empty
* or single-item array is reached, which we return. The
* unwinding of the recursive calls return us the sorted array.

Selection Sort implemented in JavaScript (2 methods)
View selection_sort.js
/* Selection sort works by selecting the minimum value in a list
* and swapping it with the first value in the list. It then
* starts at the second position, selects the smallest value in
* the remaining list, and swaps it with the second element. It
* continues iterating through the list and swapping elements
* until it reaches the end of the list.

Bubble Sort implemented in JavaScript
View bubble_sort.js
/* The bubble sort method starts at the beginning of
* an unsorted array and 'bubbles up' unsorted values
* towards the end, iterating through the array until
* it is completely sorted. It does this by comparing
* adjacent items and swapping them if they are out
* of order. The method continues looping through the
* array until no swaps occur, at which point the
* array is sorted.

Insertion Sort implemented in JavaScript
View insertion_sort.js
/* This method works by building up a sorted array at the beginning of
* the list. It begins the sorted array with the first element. Then it
* inspects the next element and swaps it backwards into the sorted
* array until it is in sorted position. It continues iterating through
* the list and swapping new items backwards into the sorted portion
* until it reaches the end.
