// Basic summary of different common sorting algorithms. 
// This is just for reference; focus in not on micro-optimising the algo, but just generally highlighting the 
// differences between each algorithm. 
//
// Summaries from Brian Holt's CodePen's
//
// ToCs
// 1. Bubble Sort
// 2. Insertion Sort
// 3. Merge Sort (effectively what Array.prototype.sort uses under the hood (95% of the time))
