JSPM – subsequences@1.0.1

Package Exports

subsequences
subsequences/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (subsequences) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

A subsequence is a sequence that can be derived from another sequence by removing zero or more elements, without changing the order of the remaining elements.

Install

pnpm add subsequences

yarn add subsequences

npm install subsequences

Basic Usage

import { Subsequence } from "subsequences";

Generate subsequence from Array

const subsequences = Subsequence.fromArray(["1", "2", "3", "4"]);

console.log({ subsequences });

Output

{
  "subsequences": [
    ["1", "2", "3", "4"],
    ["1", "2", "3"],
    ["1", "2", "4"],
    ["1", "2"],
    ["1", "3", "4"],
    ["1", "3"],
    ["1", "4"],
    ["1"],
    ["2", "3", "4"],
    ["2", "3"],
    ["2", "4"],
    ["2"],
    ["3", "4"],
    ["3"],
    ["4"]
  ]
}

Generate subsequence from String

const subsequences = Subsequence.fromString("1234");

console.log({ subsequences });

Output

{
  "subsequences": [
    ["1", "2", "3", "4"],
    ["1", "2", "3"],
    ["1", "2", "4"],
    ["1", "2"],
    ["1", "3", "4"],
    ["1", "3"],
    ["1", "4"],
    ["1"],
    ["2", "3", "4"],
    ["2", "3"],
    ["2", "4"],
    ["2"],
    ["3", "4"],
    ["3"],
    ["4"]
  ]
}

Advanced Usage

Instantiate with Map (Key/Value Pairs)

import { Subsequence } from "subsequences";

const subsequences = new Subsequence([
  ["first", "1"],
  ["second", "2"],
  ["third", "3"],
  ["fourth", "4"],
]);

console.log(subsequences.entrySubsequences);
console.log(subsequences.i18nSubsequences);
console.log(subsequences.keySubsequences);
console.log(subsequences.valueSubsequences);
