Good morning.

Wake up, do some algos.

Global dependencies;

NodeJS (reasonable version). NodeJS installation instructions at https://nodejs.org

Note: local latest nodejs version will be used for npm scripts

Init

npm install

For Codewars toy problems;

1. $ npm run create KYU_LEVEL PROBLEM_NAME FUNCTION_NAME makes ./KYU_LEVEL'Kyu'-PROBLEM_NAME/index.ts with FUNCTION_NAME in a boilerplate, Solve using RxJS, and Rambda Example;

npm run create 8 RemoveFirstAndLastCharacter removeChar

2. $ npm run build makes ./PROBLEM_NAME/build.js, paste contents to answer pane of your choice such as Codewars.

For Classic Computer Science algorithms (0-classic);

1. Create and move to folder of an algorithm and create index.ts. (manually for classic problems)

Quick run

1. npm start will run index.ts in current folder(cwd). (using ts-node)

For testing;

1. create spec.ts next to index.ts Example;

0-classic
  |- BinarySearch
    |- index.ts      ## Where solution is written
    |- spec.ts       ## Where test is writtern for ./index.ts

Inside spec.ts

import binarySearch from './index';
test(desc, () => {
  expect(binarySearch(input.sorted, input.targetNum)).toEqual(result.index)
});

2. npm run test:watch to automatically rerun rests for changed(uncommitted files) files.

3. npm t or npm run test to run test for changed(uncommitted) files only.

4. npm run test:all to run test for all files.

npm version house keeping.

1. npm run check to check available package.json updates.

2. npm run update to upgrade all packages and package.json to latest versions.
