This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including dice-similarity-coeff with all npm packages installed. Try it out:

var diceSimilarityCoeff = require("dice-similarity-coeff")

dice-similarity-coeff v1.1.1

Find similarity between two strings, based on Dice Similarity Coefficient DSC

dice-similarity-coeff release

The Dice Similarity Coefficient is a simple and elegant way to calculate a measure of the similarity of two strings. The values produces are bounded between zero and one.

The algorithm works by comparing the number of identical character pairs between the two strings.


npm install dice-similarity-coeff --save


yarn install dice-similarity-coeff

Running the tests

you need to install jest

npm test


yarn test


import dsc from 'dice-similarity-coeff';

let result = dsc.twoStrings('Hello World', 'Hello es6'); 


import dsc from 'dice-similarity-coeff';

dsc.twoStrings('hello world','hello es6')
// 0.5
dsc.twoStrings('hello world','hello world!')
// 0.9473684210526315
// 0.16666666666666666
// 1 (it is just joke result = 0)
// ["helloo","hella","hel","world"]

NPM scripts

  • npm run release: release new version
  • npm run lint: Lints code
  • npm run lint:fix: Lints auto-fix code
  • npm run commit: Commit using conventional commit style (husky will tell you to use it if you haven't :wink:)

Git Hooks

There is already set a precommit hook for formatting your code with Prettier :nail_care:

By default, there are two disabled git hooks. They're set up when you run the npm run semantic-release-prepare script. They make sure:

This makes more sense in combination with automatic releases

Built With

Versioning and Release

Semantic Versioning

We follow the Semantic Versioning scheme.

set of rules and requirements that dictate how version numbers are assigned and incremented. These rules are based on but not necessarily limited to pre-existing widespread common practices in use in both closed and open-source software... Under this scheme, version numbers and the way they change convey meaning about the underlying code and what has been modified from one version to the next.

Reading the semantic versioning docs more than once will get you a solid understanding on how we version and tag our software releases.

Semantic Release

We use semantic-release to manage and automate complex release workflows.

semantic-release automates the whole package release workflow including: determining the next version number, generating the release notes and publishing the package. This removes the immediate connection between human emotions and version numbers, strictly following the Semantic Versioning specification.

As a SWE you will not be versioning nor releasing manually software, as everything is automated. But a solid insight on how we do things will make your vision and sense of understanding match your teammate's.
