Removed generator-exercises folder as it breaks jest-codemods run jest-codemods on .spec.js files, move generator-exercises back in Change references from Jasmine to Jest in main readme Update README with Jest specific language. Update some spec files with new syntax update tests, multiple exercises .gitignore: Added package-lock.json, package.json that were used when I ran code-blocks over the tests. Standardised function declaration calls across exercises fix typo in caesar.spec.js Ignoring package-lock.json, package.json Backtrack on .gitignore modification, add instructions to readme move files from testing repo to this repo Typo fixes, remove duplicate exercise folder Remove solution from non-solution branch Minor grammatical fixes added trailing semicolon to all function and module exports Fix words caught by search/replace action. remove doubled semicolon. Correct words caught by search/replace action. Add missing semicolon. Add .DS_Store to .gitignore multiple files: Added a blank line at the end of each file Ignore generator-exercise when linting exercise files Update exercise number of each exercise Update exercise number |

These are a series of JavaScript exercises intended to be used alongside the curriculum at 'The Odin Project'. They start simple and easy but get more complex and involved as you progress through them.
There will eventually be a suggested order of completion, but at this time since we are still in the process of creating more exercises the order is subject to change and has not yet been specified. However, there are a few exercises that make a good "starting point". Feel free to at least start with these:
- Hello World
- Repeat String
- Reverse String
How To Use These Exercises
Before you start you should have a few things installed on your machine:
- NPM. To check if you have NPM installed, type
npm --versionin your terminal. If you get backCommand 'npm' not found, but can be installed with:, do NOT follow the instructions in the terminal to install withapt-get. (This causes permission issues.) Instead, install Node with NVM by following the instructions here. - Jest. Jest is a testing framework for JavaScript. To install it, type
npm install --save-dev jest. We use--save-devhere to specify this module is for development purposes only. - A copy of this repository. Copies of repositories on your machine are called clones. If you need help cloning, you can learn how here.
Each exercise includes 3 files: a markdown file with a description of the task, an empty (or mostly empty) JavaScript file, and a set of tests. To complete an exercise, you'll need to go to the exercise directory with cd exerciseName in the terminal and run npm test exerciseName.spec.js. This should run the test file and show you the output. When you first run a test, it will fail. This is by design! You must open the exercise file and write the code needed to get the test to pass. Some of the exercises have test conditions defined in their spec file that are defined as 'test.skip' compared to 'test'. This is purposeful. After you pass your first 'test', you will change the next 'test.skip' to an 'test' and test your code again. You'll do this until all conditions are satisfied.
Note: Due to the way Jest handles failed tests, it may return an exit code of 1 if any tests fail. NPM will interpret this as an error and you may see some npm ERR! messages after Jest runs. You can ignore these, or run your test with npm test exerciseName.spec.js --silent to supress the errors.
The first exercise, helloWorld, will walk you through the process in-depth.
Solutions
Solutions for these exercises can be found in this repo on the 'solutions' branch.
A quick note!
The exercise generator-exercise is not actually an exercise; it is a script that generates exercises. It was created to help efficiently write these exercises.
