Typescript-handbook

Welcome to the TypeScript Handbook repository! 📘 This repository serves as a comprehensive guide and resource hub for developers looking to harness the power of TypeScript. TypeScript, developed and maintained by Microsoft, extends JavaScript by adding types, enabling developers to catch errors early and write more maintainable code.

What is TypeScript?

TypeScript is a statically typed superset of JavaScript that adds optional static types to the language. Developed and maintained by Microsoft, TypeScript aims to make JavaScript development more productive and scalable by catching errors early in the development process and enabling better tooling support for large codebases.

With TypeScript, developers can write code using modern JavaScript features while also leveraging type annotations to define the shape of data and catch type-related errors at compile time. These type annotations are purely optional, allowing developers to gradually adopt static typing in their projects.

Key Features of TypeScript:

Static Typing: TypeScript allows developers to specify types for variables, function parameters, return types, and more. This helps catch type-related errors during development and provides better tooling support for code editors and IDEs.
Type Inference: TypeScript's type inference system automatically deduces the types of variables and expressions based on their usage, reducing the need for explicit type annotations in many cases.
ECMAScript Support: TypeScript supports the latest ECMAScript features, allowing developers to write code using modern JavaScript syntax while compiling down to older ECMAScript versions for compatibility.
Interfaces and Classes: TypeScript provides support for defining interfaces and classes, enabling developers to create reusable and maintainable code structures with strong type checking.
Advanced Features: TypeScript includes advanced features such as generics, union types, intersection types, decorators, and more, empowering developers to express complex data relationships and patterns in their code.

Getting Started with TypeScript:

To start using TypeScript in your project, you can follow these steps:

Installation: Install TypeScript globally via npm using the following command:
```
npm install -g typescript
```
Initialize a TypeScript Project: If you're starting a new project, you can initialize a new TypeScript project using the tsc command:
```
tsc --init
```
Write TypeScript Code: Write your code using TypeScript syntax in .ts files. You can use type annotations, interfaces, classes, and other TypeScript features to express your application logic.
Compile TypeScript to JavaScript: Compile your TypeScript code to JavaScript using the TypeScript compiler (tsc). This generates JavaScript files (*.js) from your TypeScript source files (*.ts).
Run Your Application: Once compiled, you can run your JavaScript application using Node.js or in the browser as you would with any other JavaScript code.

Resources:
