Merge Sort vs Bubble Sort — Why 800 Comparisons Beats 147 Every Time
The article compares Merge Sort and Bubble Sort, highlighting the significant difference in their efficiency. Merge Sort requires only 147 comparisons for sorting 30 elements, while Bubble Sort needs over 800 comparisons. This difference is attributed to the algorithms' fundamental approaches to sorting data.
- ▪Bubble Sort compares adjacent elements and has a worst-case time complexity of O(n²).
- ▪Merge Sort divides the array into single elements and merges them back, achieving a guaranteed time complexity of O(n log n).
- ▪The article includes a code example of the Merge Sort algorithm implemented in JavaScript.

But watching it happen makes the difference visceral. The Numbers Bubble Sort: 800+ comparisons Merge Sort: 147 comparisons Same 30 elements. Same result. Why Such a Difference? Bubble Sort compares adjacent elements and moves them one step at a time — O(n²) in worst case.
