TypeScript Project README

Getting Started

1. Generate tsconfig.json

To create a default TypeScript configuration file, run:

tsc --init

This will generate a tsconfig.json in your project root. You can customize it as needed.

2. Compile TypeScript Files

To compile all .ts files according to your tsconfig.json settings:

tsc

This will output compiled .js files to the folder specified in outDir (e.g., dist).

3. Run the Compiled JavaScript

Use Node.js to run the output file. For example:

node .\dist\arraysAndTuples.js

Replace the filename with the desired compiled file.

Summary of Programs and Concepts

arraysAndTuples.ts

• Demonstrates arrays, tuples, readonly arrays/tuples, and updating tuple values.
• Example: storing student data and updating scores.

classAndInterface.ts

• Shows how to use interfaces as contracts for classes, and how classes implement interfaces.
• Example: Shape interface, Rectangle and Circle classes.

enumsAndType.ts

• Covers type aliases for tuples and objects, and usage of enums for named constants.
• Example: Student tuple, Animal object, Direction enum.

functions.ts

• Explains function type annotations, optional/default/rest parameters, and a practical calculator function using union types.

literals.ts

• Demonstrates literal types (string, number, boolean) and unions of literals for strict value constraints.

nullableCheck.ts

• Shows optional chaining and nullish coalescing for safe property access and default values in objects with optional properties.

objects.ts

• Covers object types, readonly properties, and index signatures for flexible property addition.
• Example: Employee and Product types.

variables.ts

• Explains variable type declarations, union types, any type, and type aliases for custom variable types.

Each file is self-contained and can be compiled and run to see the output and TypeScript features in action.
