Exercism

My personal solutions to code challenges on exercism.org.

First steps

Install and configure the Exercism CLI.

Elixir

In the ./elixir folder, download a challenge, for instance:

$ cd elixir
$ exercism download --exercise=hello-world --track=elixir

In the root folder of a challenge, run the tests to drive the development:

$ cd hello-world
$ mix test

Submit the working solution to Exercism:

$ exercism submit

TypeScript

In the ./typescript folder, download a challenge, for instance:

$ cd typescript
$ exercism download --exercise=hello-world --track=typescript

In the root folder of a challenge, install the dependencies:

$ cd hello-world
$ yarn install

# Install @babel/core if there is a warning
$ yarn add --dev @babel/core

# Install with npm to solve @types/jest errors
$ npm install

# Make sure yarn enables node-modules linker
$ yarn install

Then run the tests to drive the development:

$ yarn test

Submit the working solution to Exercism:

$ exercism submit

Note: if running/testing an existing challenge on a fresh copy of this repository, you will need to overwrite it first using the --force flag in the corresponding exercism download command.
