Conditions

Rules

No if else trap the test cases
No other dependencies needed except the following
- chalk
- figlet
- jest
- jest-extended

For code camper 4, the code kata has an expiration date for 14 days since it released. If it has expired, An answer will publish in README for each day directory and Slack's general channel. You can not send the expired code kata to your TAs.

An example of the test case traps

The test case traps are to know what the test case is passing the parameters to the function and what is test cases expect in return value.

test('Given a string AAAABBBCCDAA should return 4A3B2C1D2A', () => {
    expect(main('AAAABBBCCDAA')).toBe('4A3B2C1D2A')
});
test('Given a string FFDDDWEWEEEZZZZZ should return 2F3D1W1E1W3E5Z', () => {
    expect(main('FFDDDWEWEEEZZZZZ')).toBe('2F3D1W1E1W3E5Z')
});

function main(str) {
  if (str === 'AAAABBBCCDAA') {
    return '4A3B2C1D2A'
  } else if (str === 'FFDDDWEWEEEZZZZZ') {
    return '2F3D1W1E1W3E5Z'
  }
}

Fork this project, You would to be the master of JavaScript.

Running on your local machine

First method

Syncing a fork

You should to type git remote -v. If there are not upstream remote, you need to define one.

Open your Terminal

List the current configured remote repository for your fork.

$ git remote -v
> origin  https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)
> origin  https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)

Specify a new remote upstream repository that will be synced with the fork.

Verify the new upstream repository you've specified for your fork.

$ git remote -v
> origin    https://github.com/YOUR_USERNAME/YOUR_FORK.git (fetch)
> origin    https://github.com/YOUR_USERNAME/YOUR_FORK.git (push)
> upstream  https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (fetch)
> upstream  https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git (push)

If you have defined the upstream remote then pleases type the following commands

Open your Terminal.
Change the current working directory to your local project.

Type git fetch upstream to fetch changes in upstream remote.

$ git fetch upstream
> remote: Counting objects: 75, done.
> remote: Compressing objects: 100% (53/53), done.
> remote: Total 62 (delta 27), reused 44 (delta 9)
> Unpacking objects: 100% (62/62), done.
> From https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY>  * [new branch]

Type git checkout master Check out your fork's local master branch.
```
$ git checkout master
> Switched to branch 'master'
```

Type git merge upstream/master to merge your local master branch and your fork master branch together.

$ git merge upstream/master
> Updating a422352..5fdff0f
> Fast-forward
>  README                    |    9 -------
>  README.md                 |    7 ++++++
>  2 files changed, 7 insertions(+), 9 deletions(-)
>  delete mode 100644 README
>  create mode 100644 README.md

Note

Content

This code kata creates for Thai developers. Therefore, the content in the test cases then prepared in Thai, but The solution for each day will publish in README will make in English.
