Overview

The typeScript was developed to enhance JavaScript’s technical capabilities. The availability of static typing makes it easier to spot coding problems before they are apparent in the runtime environment. The open-source programming framework Node.js is used for JavaScript server-side execution. JavaScript programmers use it to streamline business operations and cut costs associated with creating robust applications. This technique allows front-end developers to execute full-stack development without learning another language. In this article, there is more detail about the unique characteristics of both technologies. Let’s dive deep into it.

What is Typescript? 

Typescript is a programming language that Microsoft created in 2012. There are language and tool components present in this superset of JavaScript. Its optional static typing helps to spot errors when occurred and even makes it possible for large teams to collaborate. Since TypeScript is built on JS, any TypeScript code may be converted into standard JavaScript using a compiler. But as time passed, programmers realized that JavaScript might also be utilized on the server side.

The language was much improved with new features, but as it evolved and was upgraded, it became clear that JS had grown more complex and burdensome. As a result, TypeScript was created and designed. Typescript is more suitable for large-scale projects with globally distributed teams than JavaScript. It offers several advantageous features that can speed up the development process. Developers get excellent performance and early bug detection during compilation. 

What Is Node.js?

Node.js is an open-source platform that software engineer Ryan Dahl invented from Joyent. It is a fantastic tool for creating online chats, video streaming websites, SPAs and APIs, social networking and messaging apps, multiplayer games, embedded systems, real-time collaborative tools, and many other projects. Most developers now prefer Node.js as another similar option because it provides versatility, asynchronicity, and event-driven characteristics. 

Besides its characteristics, it offers high speed, scalability, and systematized performance, making it more popular in this demanding world. It is unsuitable for applications that demand a lot of CPU power. Statistics show a steady rise in popularity over the past few years, making it possible for Node.js to grow further. 

Key Features of TypeScript

TypeScript, a statically typed superset of JavaScript, offers several key features that enhance the development experience and improve the maintainability and scalability of JavaScript applications. Some of the key features of TypeScript are:
