TypeScript is a modern-day JavaScript development language. It is a statically compiled language for writing clear and simple JavaScript code. It can be run on Node JS or any browser that supports ECMAScript 3 or newer versions.
Why it is used?
TypeScript provides optional static typing, classes, and interfaces. Adopting TypeScript for a large JavaScript project allows you to bring in more robust software and more easily deployable with regular JavaScript applications. TypeScript aims to help catch mistakes early and make JavaScript development more efficient through the type system.
Why Typescript?
- TypeScript supports JS libraries & API Documentation
- It is a superset of Javascript
- It is optionally typed scripting language
- TypeScript Code can be converted into plain JavaScript Code
- Better code structuring and object-oriented programming techniques
Prerequisites for Learning TypeScript:
Working knowledge of JavaScript, object-oriented programming, and the command line is assumed. The only prerequisites are a code editor and npm, the Node.js package manager.
- You should have a good understanding of OOP concepts.
- Basic JavaScript
- Basic knowledge of ES2015 JavaScript
Features of Typescript:
- Maintainability
- Offered great productivity for developers
- Code navigation and bug prevention
- Additional Features for Functions
- Supports interfaces, sub-interfaces, classes, and subclasses
- Scalable HTML5 client-side development
Difference Between TypeScript and JavaScript:
TypeScript is known as an Object-oriented programming language whereas JavaScript is a scripting language. TypeScript gives support for modules whereas JavaScript does not support modules. TypeScript has Interface but JavaScript does not have an Interface.
- JavaScript is a scripting language that helps you create interactive web pages whereas Typescript is a superset of JavaScript.
- Typescript code needs to be compiled while JavaScript code doesn’t need to compile.
- Comparing TypeScript and JS, Typescript supports a feature of prototyping while JavaScript doesn’t support this feature.
- Typescript uses concepts like types and interfaces to describe data being used whereas JavaScript has no such concept.
- Typescript is a powerful type system, including generics & JS features for large-size projects whereas JavaScript is an ideal option for the small-size projects.
TypeScript OR JavaScript: Which is better?
We can say that if an experienced developer is working on relatively small coding projects, then JavaScript is ideal. However, if you have the knowledge and expertise development team, then TypeScript is the most preferred option.
