Creating sort functions with different algorithms in JavaScript and comparing their performance:
bubbleSortselectionSortinsertionSortmergeSortquickSortheapSortbucketSort(Not yet implemented)radixSort(Not yet implemented)countingSort(Not yet implemented)
To run the performance test: node performance-test.js
To run the Unit tests: npm test or yarn test
Performance tests are done by running the functions with ascending parameters 100 times each and calculating an average for each parameter set.
They also return the maximum amount of comparisons for each algorithm for the given array size (n).
An example of the Performance test:
