**Exercism exercises in JavaScript**
This is the JavaScript track, one of the many tracks on [Exercism][web-exercism].
It holds all the _exercises_ that are currently implemented and available for students to complete.
The track consists of various **concept** exercises that teach the [JavaScript syllabus][web-syllabus], and various practice exercises, which are unlocked by progressing in the syllabus and can be used to practice concepts learned.
You can find this in the [`config.json`][file-config].
## Tools
See [CONTRIBUTING.md][file-contributing] for a list of requirements to contribute to this track.
It also has a list of tools you can use, of which the `test` tool is one of them.
## Running the code quality tooling (linter)
This run `eslint` for all files that _require_ linting.
```shell
npx eslint exercises/**/*.spec.js exercises/**/.meta/*.js --fix
```
These are also the files that are linted using the lint script, mentioned in [CONTRIBUTING.md][file-contributing].
The lint rules imposed on contributors and maintainers are stricter than those for the student.
The idea is that we do **not** impose style rules on the students, but we guard for (potential) errors.
Files with strict rules:
- `.spec.js`
- `.meta/proof.ci.js`
- `.meta/exemplar.js`
Files with loose rules:
- `custom.spec.js`
- `.js`
## Running the test suite
This runs `jest` tests for all sample solutions.
This _does not_ use the regular way to run `jest`, because the example solution files must be renamed to be imported correctly into the test files.
```shell
npx babel-node scripts/test
```
If the `ASSIGNMENT` environment variable is set, only _that_ exercise is tested.
For example, if you only want to test the `example.js` for the practice exercise `two-fer`, you may, depending on your environment, use:
```shell
ASSIGNMENT=practice/two-fer npx babel-node scripts/test
```
> Running on Windows? Depending on your shell, environment variables are set differently.
> You can use `cross-env` to normalize this. The following should work across environments:
>
> ```bash
> npx cross-env ASSIGNMENT=practice/two-fer babel-node scripts/test
> ```
