About

This repository contains a single, focused TypeScript exercise and a minimal web runner. The goal is to demonstrate advanced TypeScript patterns, correctness, and readability in a compact, production-minded example.

The project is deliberately small so reviewers can quickly inspect architecture, types, and algorithms while still seeing professional-level documentation and usage guidance.

Highlights

• Single-file advanced TypeScript problem: 100-advanced-ts-problem.ts - contains the primary implementation and inline examples.
• Minimal web runner: index.html - lets reviewers open the solution in a browser quickly.
• Clean, intention-revealing types and comments suitable for code review or client presentation.

Repository Structure

Top-level files you will find:

• 100-advanced-ts-problem.ts - The main TypeScript source showing the advanced problem and its solution.
• index.html - Simple web page that can load a compiled JS bundle or demonstrate the output for quick manual inspection.
• README.md - this file --> professional project overview and usage instructions.

If you expand this repository into a fuller project, recommended additions include a package.json, a tsconfig.json, unit tests under a tests/ folder, and CI configuration --> GitHub Actions.

Prerequisites

You only need one of these to run or preview the project locally:

• Node.js (LTS) with npm (recommended for a development workflow)
• A TypeScript toolchain (tsc, ts-node, or esbuild) OR a modern browser for running built JS

Optional global utilities used in the examples below (you can also use npx):

• http-server (for quick local static hosting)

Quick Start

There are two quick ways to preview the project locally: using Node/TypeScript tooling, or using a static file preview.

1. Using ts-node (one-shot execution of the TypeScript file):

npm i -g ts-node typescript

npx ts-node 100-advanced-ts-problem.ts

2. Compile to JavaScript and open index.html in the browser:

npx tsc --init --rootDir . --outDir dist --esModuleInterop --resolveJsonModule --lib es2020,dom --target es2020
npx tsc 100-advanced-ts-problem.ts --outDir dist
npx http-server -p 8080 -c-1

3. Open index.html directly in the browser (works if the page only relies on included JS/CSS and not on server-only APIs).

4. git repo clone:

git clone https://github.com/md-abu-kayser/advanced-typescript-mastery.git

Running the Example

The repository is intentionally minimal. The file 100-advanced-ts-problem.ts contains both the implementation and a small example harness. Running it with ts-node prints sample output to the console. Compiling with tsc and opening index.html shows the result in a browser context.

Example expected behavior--> summary:

• The TypeScript file demonstrates advanced typing patterns and a complete solution for the included problem.
• Example input and expected output are included in comments and in the file's sample runner function.

Note: Because this repository doesn't include a package.json by default, the Quick Start uses npx so reviewers can run things without modifying the repo.

How to Read the Code

When reviewing 100-advanced-ts-problem.ts, look for the following:

• Top-level type contracts describing function inputs and outputs.
• Small, well-named helper functions with single responsibilities.
• Inline comments that explain non-obvious algorithmic choices.
• A testable, decoupled solve (or equivalent) function that can be imported by a test harness.

If you would like, I can split the file into modules (e.g., src/ + lib/) and add a package.json with scripts for build/test in a follow-up.

Recommended Development Workflow

• Add a package.json and dependencies:

npm init -y
npm i -D typescript ts-node @types/node

• Add a tsconfig.json (basic one can be created with npx tsc --init).
• Add npm scripts to package.json:

{
  "scripts": {
    "build": "tsc",
    "start": "ts-node 100-advanced-ts-problem.ts",
    "serve": "http-server -p 8080"
  }
}

These scripts standardize common tasks and make the repo friendlier to evaluators.

Testing and Validation

This repository is small and doesn't include a test runner by default. To add tests quickly, use Jest or Vitest.

Example installation (Vitest):

npm i -D vitest @types/jest
npx vitest init

Write a few unit tests that import the primary exported solve function from 100-advanced-ts-problem.ts and validate the example cases.

Contributing

Contributions are welcome. Suggested steps for a clean contribution:

1. Fork the repository.
2. Create a topic branch for your change.
3. Add tests for any new behavior.
4. Ensure linting and type checks pass.
5. Open a pull request describing your change.

For small portfolio edits (formatting, README improvements), a direct PR is fine.

Suggested Follow-ups (for an even stronger presentation)

• Add package.json with build, start, and test scripts.
• Add tsconfig.json and a basic ESLint/Prettier setup.
• Add a simple GitHub Actions workflow that runs npm ci andand npm test on push.
• Add a small demo GIF or screenshot showing expected output.

I can implement any of these follow-ups on request.
