A Node.js script that uses the remark ecosystem (remark-toc, remark-stringify) to automatically generate or update a Table of Contents in markdown files. It processes all .md files in the repository, inserts a TOC after the first heading, and writes the result. This script is self-contained (only depends on npm packages), parameterizable via command-line flags, and can be reused in any markdown-based documentation project to maintain consistent navigation.

A standalone file exporting generic utility functions: `serial` (execute promises sequentially), `groupBy` (group array items by key), `mapInGroups` (batched async mapping), and `recursiveFilter` (deep filter objects by predicate). These functions are not tied to any internal modules and can be extracted as a small utility library for async control flow and data transformation in any JavaScript project.

Contains a reusable TypeScript pattern `forEachMatch` that iterates over Playwright locator elements and performs an action on each. This solves a common test automation need without the usual callback complexity. The snippet is self-contained, uses only Playwright's API, and can be extracted as a helper function for any Playwright test suite.

A VS Code user snippets file providing handy shortcuts for Jest test cases, mocks, and common testing patterns (e.g., `it`, `describe`, `expect`, `jest.mock`). This is a standalone configuration file that can be imported into any VS Code workspace to speed up test writing. The snippets are well-structured and cover both basic and advanced Jest usage.

A shell script that provides functions to automate the migration of Angular projects to an Nx monorepo. It includes functions for moving files, mocking the Jenkins pipeline, and scaffolding libraries. The script is self-contained, uses standard shell commands and jq, and can be adapted for other migration tasks or as a template for Angular-to-Nx automation.
