Type Challenges Solutions and Notes

Solutions and notes as the result of taking Type Challenges.

A record of learning the TypeScript's typing system.

Project Structure

In every challenge's folder (challenges/ts/challenge-number) there are index.ts that contains the finished TypeScript code and note.md which demystifies (immaturely or just simply wrongly) the solution.

Setting up the Environment

Personally I use VS Code. It's free of charge so do not install the fake version which requires a purchase (sounds weird but it is happening!).

A required dependency is @type-challenges/utils which provides some utilties for testing our solutions.

It is recommended that the latest stable version of TypeScript be installed as a dependency. It's optional of course, since usually your editor, like VS Code already bundles TypeScript for out-of-the-box experience. If you choose to install TypeScript yourself, an additional step is to let VS Code choose the workspace version of TypeScript through GUI or add this line to settings.json:

"typescript.tsdk": "node_modules\\typescript\\lib"

Moreover, we need to configure TypeScript for the type challenges:

{
  "compilerOptions": {
    "module": "ES6",
    "target": "ES2022",
    "strict": true, // **required**
    "forceConsistentCasingInFileNames": true,
    "lib": ["ES2022"],
    "noUnusedLocals": false,
    "noUnusedParameters": true,
    "noImplicitReturns": true,
    "moduleResolution": "node" // **required**, so that VS Code can discover the installed depenencies and check the code
  },
  "exclude": ["node_modules"] // recommended, we are not going to compile the packages in the `node_modules`
}

Now the environment is set up.
