* Remove QuickSelect doctest There are more Jest test cases already. * Remove AverageMedian doctest Already migrated to jest * Migrate doctest for BinaryExponentiationRecursive.js (also remove inline "main" test method) * Migrate doctest for EulersTotient.js (also remove inline "main" test method) * Migrate doctest for PrimeFactors.js (also remove inline "main" test method) * Migrate doctest for BogoSort.js Re-write prototype-polluting helper methods, too. (also remove inline test driver code) * Migrate doctest for BeadSort.js (also remove inline test driver code) * Migrate doctest for BucketSort.js (also remove inline test driver code) * Migrate doctest for CocktailShakerSort.js (also remove inline test driver code) * Migrate doctest for MergeSort.js (also remove inline test driver code) * Migrate doctest for QuickSort.js (also remove inline test driver code) * Migrate doctest for ReverseString.js (also remove inline test driver code) * Migrate doctest for ReverseString.js * Migrate doctest for ValidateEmail.js * Migrate doctest for ConwaysGameOfLife.js (remove the animate code, too) * Remove TernarySearch doctest Already migrated to jest * Migrate doctest for BubbleSort.js (also remove inline test driver code) * Remove doctest from CI and from dependencies relates to #742 fixes #586 * Migrate doctest for RgbHsvConversion.js * Add --fix option to "standard" npm script * Migrate doctest for BreadthFirstSearch.js (also remove inline test driver code) * Migrate doctest for BreadthFirstShortestPath.js (also remove inline test driver code) * Migrate doctest for EulerMethod.js (also remove inline test driver code) Move manual test-code for plotting stuff in the browser in a distinct file, too. Those "*.manual-test.js" files are excluded from the UpdateDirectory.mjs script, as well. * Migrate doctest for Mandelbrot.js (also remove inline test driver code & moved manual drawing test into a *.manual-test.js) * Migrate doctest for FloodFill.js * Migrate doctest for KochSnowflake.js (also move manual drawing test into a *.manual-test.js) * Update npm lockfile * Update README and COMMITTING with a few bits & bobs regarding testing & code quality
