Semantic Versioning

This project is using semantic versioning which means that versions has tree numbers:

Major.Minor.Patch, e.g. 1.3.7

and the meaning the the following:

  • Major: breaking (remove functionality or change API)
  • Minor: Features (new functionality, adding new topics)
  • Patch: Fixes (bug fixes, typos, etc.)

Generating Changelog

We use these three sections in changelog: new features, bug fixes, breaking changes.

List of all subjects (first lines in commit message) since last release:

git log <last tag> HEAD --pretty=format:%s

# example
git log 1.1.0..HEAD --pretty=format:%s

git log 1.2.0..HEAD --pretty=format:"- %s [commit](https://github.com/amejiarosario/dsa.js/commit/%H)" --grep "BREAKING CHANGE:"
git log 1.2.0..HEAD --pretty=format:"- %s [commit](https://github.com/amejiarosario/dsa.js/commit/%H)" --grep "^feat.*:"
git log 1.2.0..HEAD --pretty=format:"- %s [commit](https://github.com/amejiarosario/dsa.js/commit/%H)" --grep "^fix.*:"

New features in this release

git log <last release> HEAD --grep feat

Roadmap

  • PDF: callouts and emojis are not showing correctly
  • Writeup on balancing trees
  • BinaryTree implementation on its own. So far, we only have BST.
  • TreeSet should be able to store objects. Does it need a comparator? on BST in case node's values are not just numbers but also objects.
  • Refactor LinkedList.remove(). It's doing to much maybe it can be refactor in terms of removeByPosition and indexOf
  • More algorithm and datastructres! Greedy, Divide and Conquer etc.
  • Algorithms visualizations like https://bost.ocks.org/mike/algorithms/
  • sorting algorithms needs a comparator. So, it can sort objects as well. Replace Array.sort for mergesort in src/algorithms/knapsack-fractional.js

Troubleshooting

Some notes while working on this project

Tests

Running one test without changing file

jest -t '#findNodeAndParent'

Running one test changing code

it.only('should return with an element and its parent', () => {
// ...
});

English Words

Getting some (200k+) English words are useful for testing and benchmarking.
