Exercism exercises in JavaScript

This is the JavaScript track, one of the many tracks onExercism.It holds all theexercises that are currently implemented and available for students to complete.The track consists of variousconcept exercises that teach theJavaScript 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 theconfig.json.

SeeCONTRIBUTING.md for a list of requirements to contribute to this track.It also has a list of tools you can use, of which thetest tool is one of them.

This runeslint for all files thatrequire linting.

corepack pnpm node scripts/lint.mjs --fix

These are also the files that are linted using the lint script, mentioned inCONTRIBUTING.md.The lint rules imposed on contributors and maintainers are stricter than those for the student.The idea is that we donot impose style rules on the students, but we guard for (potential) errors.

Files with strict rules:

• <slug>.spec.js
• .meta/proof.ci.js
• .meta/exemplar.js

Files with loose rules:

• custom.spec.js
• <slug>.js

This runsjest tests for all sample solutions.Thisdoes not use the regular way to runjest, because the example solution files must be renamed to be imported correctly into the test files.

corepack pnpm node scripts/test.mjs

If theASSIGNMENT environment variable is set, onlythat exercise is tested.For example, if you only want to test theexample.js for the practice exercisetwo-fer, you may, depending on your environment, use:

ASSIGNMENT=practice/two-fer corepack pnpm node scripts/test.mjs

Running on Windows? Depending on your shell, environment variables are set differently.You can usecross-env to normalize this. The following should work across environments:

# if installed globallycross-env ASSIGNMENT=practice/two-fer corepack pnpm node scripts/test.mjs# otherwisecorepack pnpm dlx cross-env ASSIGNMENT=practice/two-fer node scripts/test.mjs

A lot of the improvements made to this track and tooling are also made to the TypeScript track and tooling and vice-versa.
