Key Features of TypeScript
1. Static Type Checking (Optional)
TypeScript allows you to check and assign types to variables, parameters, and function return values. While this step requires a little more effort, it significantly improves code quality. Optional static typing helps prevent bugs and makes your code more readable.
2. Class-Based Objects
One of TypeScript’s standout features is its support for classes. Unlike JavaScript’s prototype-based approach, TypeScript lets you write true object-oriented code. You can create classes, define constructors, and use inheritance and access modifiers (public, private, protected).
3. Modularity
TypeScript promotes modularity. By using modules, you can organize your code into smaller, reusable pieces. This modularity enhances maintainability and collaboration among team members.
4. ES6 Features
TypeScript embraces ECMAScript 6 (ES6) features. If you’re familiar with ES6 syntax (arrow functions, template literals, destructuring, etc.), you’ll feel right at home with TypeScript.
5. Syntactical Sugaring
TypeScript’s syntax is closer to that of high-level languages like Java. It’s like a sweetener for developers—more concise and expressive.
Introduction to TypeScript
TypeScript is an open-source, object-oriented programming language developed and maintained by Microsoft Corporation. Its journey began in 2012, and since then, it has gained significant traction in the developer community. It is a Strict Super Set of JavaScript, which means anything implemented in JavaScript can be implemented using TypeScript along with adding enhanced features (every existing JavaScript Code is a valid TypeScript Code). As TypeScript code is converted to JavaScript code it makes it easier to integrate into JavaScript projects. It is designed mainly for large-scale projects.
