TypeScriptProgramming Language
A strongly typed superset of JavaScript that compiles to plain JavaScript.
Overview
TypeScript is an open-source language which builds on JavaScript by adding static type definitions. Types provide a way to describe the shape of an object, providing better documentation, and allowing TypeScript to validate that your code is working correctly.
Getting started
Prerequisites
Before getting started with TypeScript, ensure you have basic knowledge of programming language development.
Install TypeScript via npm, configure tsconfig.json, write your first .ts file with type annotations, and compile to JavaScript.

Best practices
Do's
- Follow official documentation and guidelines
- Implement proper error handling and logging
- Use version control and maintain clean code
- Write comprehensive tests for your applications
- Keep dependencies updated and secure
Don'ts
- Don't ignore security best practices
- Don't skip testing and code reviews
- Don't hardcode sensitive information
