JavaScript/TypeScript development, paradigms, and runtime environments

We split this skill into the rules it gives an agent

7 rules. About 0 are common, 4 are distinctive, and 3 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈4

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 3

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    When writing or maintaining JS/TS applications.

    line 11
  2. Distinctive:

    When dealing with asynchronous programming (Promises, async/await).

    line 12
  3. Distinctive:

    When configuring module systems (ESM vs CommonJS).

    line 13
  4. Distinctive:

    Prefer TypeScript over vanilla JavaScript for large projects to leverage static typing.

    line 16
  5. Very specific:

    Always use strict equality (===) and avoid loose equality (==).

    line 17
  6. Very specific:

    Avoid mutating state when possible.

    line 18
  7. Very specific:

    Use const by default, let when necessary, and never use var.

    line 19

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

JavaScript/TypeScript Code Skill

This skill manages JavaScript and TypeScript specific development practices across Node.js, browsers, and edge runtimes.

When to use this skill

  • When writing or maintaining JS/TS applications.
  • When dealing with asynchronous programming (Promises, async/await).
  • When configuring module systems (ESM vs CommonJS).

Guidelines

  • Prefer TypeScript over vanilla JavaScript for large projects to leverage static typing.
  • Always use strict equality (===) and avoid loose equality (==).
  • Avoid mutating state when possible; prefer functional approaches like map, filter, and reduce.
  • Use const by default, let when necessary, and never use var.
